Fix parquet arrow read batch bug
#2811
The original code was to determine the number of rows in the batch based on the number of rows in the parquet RowGroup.But now it's a batch take 65535 lines. So when parquet row greater than 65535，the number of batch don't match the number of rowgroup. The code using the field "_current_line_of_group" as a position of array can cause the data to be out of array cause be crash
This CL supports arrow's zero copy read interface, which can make code
comply with arrow 0.15.
And the schema change unit test has some problem, I disable it in run-ut.sh
Currently, we do not support parsing encoded/compressed columns in file path, eg: extract column k1 from file path /path/to/dir/k1=1/xxx.csv
This patch is able to parse columns from file path like in Spark(Partition Discovery).
This patch parse partition columns at BrokerScanNode.java and save parsing result of each file path as a property of TBrokerRangeDesc, then the broker reader of BE can read the value of specified partition column.
