Hubert Zhang closed HAWQ-297. ----------------------------- Resolution: Fixed fixed > Double check hdfs and split length equals to metadata logic length. > ------------------------------------------------------------------- > > Key: HAWQ-297 > URL: https://issues.apache.org/jira/browse/HAWQ-297 > Project: Apache HAWQ > Issue Type: Improvement > Components: Core > Reporter: Hubert Zhang > Assignee: Hubert Zhang > > for each table, we store file logic length in pg_aoseg metadata table. > when scanning tables, we obtain blocks information from HDFS(or cache) > we need to ensure the file length in HDFS equals to the logic length of file > in pg_aoseg. > Again, we also need to ensure after we assign each blocks to virtual > segments, the total length of splits equals to the logic length of file in > pg_aoseg. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
