"Double quotes are no getting removed even after using org.apache.hadoop.hive.serde2.OpenCSVSerde",

So here are my question\n\n\nWhere I am going wrong\nSay If I am having multiple quoteChar to be escaped, for example, I need to remove both single and double quotes from my input data. How can I achieve this using opencsv serde.\nAs per Apache [https://cwiki.apache.org/confluence/display/Hive/CSV+Serde#CSVSerde-Usage][1]\neven if I have not defined the quoteChar and escapeChar, it should automatically pick double quotes with escape char as \"\\\" and should automatically remove double quotes from data. But why its not happening in my code"

"Identify rows where time difference is insufficient SQL Server 2008 R2",
"I have reviewed and tried numerous codes samples on the site but am no closer to solving my problem. I think is partly due to my coding skills and partly a limitation of SQL Server 2008R2 lack of LAG. \n\nMy table Clock__Times has tens of thousands of rows with these columns:\n\nEMP_NO, ACCOUNT_DATE, IN_STAMP, OUT_STAMP\n\n\nA row is added when the clock out activity occurs. Potentially multiple rows can be added for a given employee each day. I need to identify rows and count the occasions for an employee within a given time span (ACCOUNT_DATE BETWEEN D1 & D2) when the time between clock out time (OUT_STAMP) and the next clock in time (IN_STAMP) for that employee is less than X hours but greater than Y hours. \n\nI have tried a variety of JOINs but they are always wrong as I have to compare the OUT_STAMP on one row with the IN_STAMP of the next row added for the same employee. \n\nThe Y value is to avoid clock in and out activity over lunch and would probably have a value of say 2 hours. The X value is to identify employees who do not get sufficient time off between shifts say 10 hours.\n\nI will eventually have to scale this up to identify all employees who within a period of time have had insufficient time off."

"Indexed GL_TRIANGLES vs. indexed GL_TRIANGLE_STRIP",

But I believe there is a case that has not been considered enough.\n\nIndexed triangles are rendered like this in OpenGl:\n\nglDrawElements(GL_TRIANGLES, ...);\n\n\nBut for some reason a lot of people consider rendering strips only in this way:\n\nglDrawArrays(GL_TRIANGLE_STRIP, ...);\n\n\nOut there there are some very good indexers (Forsyth, Tipsify to name a few) that optimize your mesh to be convenient for the GPU transform cache to be rendered in GL_TRIANGLES mode. Ideally they can achieve like 0.5 rendered vertices per triangle or something like that.\n\nBut why not doing this?\n\nglDrawElements(GL_TRIANGLE_STRIP, ...);\n\n\nI mean, you combine the low index bandwidth of strip rendering with the efficient GPU transform cache usage that the above indexers provide. With few modifications, am I right in saying that a strip indexer that optimizes the strip to be also Tcache-friendly can be a good idea?\n\nProbably it won't reach the 0.5 goal, but at least a 0.6 perhaps? Also, don't forget the massive index bandwidth gain (potentially one third against GL_TRIANGLES)."

Now this will compile and create the jar. When I run spark-submit with the jar with dependencies, I get a no such method error for some methods in the org.bouncycastle.util package. The main one being:\n\njava.lang.NoSuchMethodError: org.bouncycastle.util.Strings.newList()Lorg/bouncycastle/util/StringList;\n\n\nwhen trying to just run Strings.newList(); in the main class. So I ran mvn dependency:tree to see if there were multiple versions of bouncy castle, and I only saw the dependencies I added to the pom. \n\nHere is the really weird part: if I build the jar and run it with java -jar jar-name-jar-with-dependencies.jar (meaning not through spark-submit) the dependency gets added just fine, and I do not see any errors. So with that in mind, what would be the differences between the spark submit jar and just running the jar directly?\nWhy would one work and the other fail? I have tried running it on different machines, such as an emr job, and I still see the same error. (and to avoid this getting asked, I am using the jar-with-dependencies jar for the spark job)\n\nOne final note, I have seen this post Bouncy castle no such method error, and it doesn't apply, since I can get the jar to run when I just run the jar by itself without spark-submit."

The app uses about 150 cloudlets = 30 GHz CPU + 20GB RAM.\n\nHow would you recommend setting up the cluster in AWS? What instance types are the best for Kubernetes master and minions?

"SSL-Does a server certificate bind to a specific machine?",
"Recently we created a server with tomcat and we also add SSL support for this little server. For SSL support, we need a certificate which issued by a third issuer like Entrust, Thawte etc. \n\nA colleague said to me that the certificate is binding to a specific machine. That's once we got the issued certificate, then this cert can't be used in another machine. \n\nI doubt this completely because the CSR doesn't contain any info of the machine. Is that true?\n\nThanks"

"JQuery autocomplete: trigger",
"As we all know, javax.swing.JComboBox is a dropdown selection having E elements in it. When setting .setEditable(true), we now can make that JComboBox also a JTextField for other E element.\n\nAfter searching with Google on this, it returned to us a suggestion of using by JQuery about autocomplete presented here. Autocomplete is working on the selection but here's the problem, we need to trigger the onChange attribute that contains the ${remoteFunction} to render a particular template on the update attribute of the said ${remoteFunction}.\n\n<g:select \n id=\"itemSelectId\"\n onChange=\"${remoteFunction(\n controller:'item', action:'itemSelect',\n update:[success:'updateItemId'],\n params:'\\'id=\\' + escape(this.value)'\"/>\n<div id=\"updateItemId></div>\n\n\nAnd on the <script> provided on the link we just change #combobox to #itemSelectId."

"Is it necessary to create user defined exceptions for each errors",

I have created individual user defined exceptions for each error. Those classes doing nothing but returning error messages.\n\nReasons to create individual exceptions:\n\n\nDeveloper should not missed out handling any error situations, when i create exception it will show error by default they have to handle to handle the situation.\nWhile logging it will me more explanatory when i go through log if i create individual user defined exceptions for my error scenarios.\n\n\nNow I am wondering:\n\n\nIs it necessary to create individual user defined exceptions for each error scenario?\nHow most people handle errors and user defined exceptions in a better way?"
