Mithun Radhakrishnan updated HIVE-11456: ---------------------------------------- Attachment: HIVE-11456.1.patch The fix. The hard-codes for {{part}} in the file-names have been switched to use the conf-setting for {{"mapreduce.output.basename"}}. Sorry for the delay. > HCatStorer should honor mapreduce.output.basename > ------------------------------------------------- > > Key: HIVE-11456 > URL: https://issues.apache.org/jira/browse/HIVE-11456 > Project: Hive > Issue Type: Bug > Affects Versions: 1.2.0 > Reporter: Rohini Palaniswamy > Assignee: Mithun Radhakrishnan > Priority: Critical > Attachments: HIVE-11456.1.patch > > > Pig on Tez scripts with union directly followed by HCatStorer have a problem > due to HCatStorer not honoring mapreduce.output.basename and always using > part. Tez sets mapreduce.output.basename to part-v000-o000 (vertex id > followed by output id). With union optimizer, Pig uses vertex groups to write > directly from both the vertices to the final output directory. Since hcat > ignores the mapreduce.output.basename, both the vertices produce > part-r-0000<n> and when they are moved from the temp location to the final > directory, they just overwrite each other. There is no failure and only one > of the files with that name makes it into the final directory. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
