Hudson commented on HIVE-3707: ------------------------------ Integrated in Hive-trunk-hadoop2 #54 (See [https://builds.apache.org/job/Hive-trunk-hadoop2/54/]) HIVE-3707 Round map/reduce progress down when it is in the range [99.5, 100) (Kevin Wilfong via namit) (Revision 1409680) Result = ABORTED namit : http://svn.apache.org/viewcvs.cgi/?root=Apache-SVN&view=rev&rev=1409680 Files : * /hive/trunk/ql/src/java/org/apache/hadoop/hive/ql/exec/HadoopJobExecHelper.java > Round map/reduce progress down when it is in the range [99.5, 100) > ------------------------------------------------------------------ > > Key: HIVE-3707 > URL: https://issues.apache.org/jira/browse/HIVE-3707 > Project: Hive > Issue Type: Improvement > Components: Logging, Query Processor > Affects Versions: 0.10.0 > Reporter: Kevin Wilfong > Assignee: Kevin Wilfong > Priority: Minor > Fix For: 0.10.0 > > Attachments: HIVE-3707.1.patch.txt > > > In HadoopJobExecHelper the mapProgress and reduceProgress are the value of > these counters taken from the running job rounded to an integer percentage. > This means that e.g. if the mappers are 99.5% done this is stored as 100%. > One of the most common questions I see from new users is, the map and reduce > both report being 100% done, why is the query still running? > By rounding down the value in this interval so it's only 100% when it's > really 100% we could avoid that confusion. > Also, the way it appears the QueryPlan and MapRedTask determine if the > map/reduce phases are done is by checking if this value == 100. I couldn't > find anywhere where they're used for anything significant, but they're > reporting early completion. -- This message is automatically generated by JIRA.
