issue #290, hive map conversion to parquet schema
remove originalType check for typeEquals of GroupType and add tests for HiveSchemaConverter
remove originalType check for typeEquals of GroupType and add tests for HiveSchemaConverter
Merge branch 'master' of github.com:tongjiechen/parquet-mr

remove unnecessary tab and spaces
1. upgrade scrooge dep to 3.12.1  2. fix bug when an enum field is optional, scroogeSchemaConverter would fail
generate splits by min max size, and align to HDFS block when possible
fix enum to be upper case
local variable of hdfsBlock
fix missing space
check maxSplit size must be greater or equal to minSplitSize
maxSplitSize should always be positive
separate out getParquetInputSplit method in the SplitInfo class, reduce LOC in the generateSplit method
move parseMessageType out of the loop
1. remove unused readSupportClass parameter from generateSplit method; 2. double check split min max to be postive in the getSplits method; 3. explicit import java.util.xx in test
add more tests so the hdfsSize is not multiple of rowGroup size
min split size default to 0
add non-negative check in generateSplits method
better message
create a getStartingPos in ColumnChunkMetaData
make SplitInfo contain the hdfsBlock
