Attila Jeges has uploaded a new patch set (#5). Change subject: IMPALA-3079: Fix sequence file writer ......................................................................
IMPALA-3079: Fix sequence file writer Before the fix, sequence file writer produced corrupt files in some cases. Steps to reproduce: SET ALLOW_UNSUPPORTED_FORMATS=1; create table store_sales_seq_snap like tpcds_parquet.store_sales stored as SEQUENCEFILE; insert into store_sales_seq_snap partition(ss_sold_date_sk) select * from tpcds_parquet.store_sales where ss_sold_date_sk between 2450816 and 2451200; The insert statement produces a corrupt file that cannot be read back. This change fixes: - The implementation of zero-compressed encoding in ReadWriteUtil class. - The calculation of block sizes in SnappyBlockCompressor class. - Creating record/block compressed sequence files in HdfsSequenceTableWriter class.
