Rui Li commented on HIVE-15054:
-------------------------------
Thanks [~aihuaxu] for the investigation and update!
The patch looks good. But I find the comments a little bit confusing. How about
something like this
{code}
// Hive requires this TaskAttemptId to be unique. MR's TaskAttemptId is
composed of "attempt_timestamp_jobNum_m/r_taskNum_attemptNum". The counterpart
for Spark should be "attempt_timestamp_stageNum_m/r_partitionId_attemptNum".
When there're multiple attempts for a task, Hive will rely on the partitionId
to figure out if the data are duplicate or not (see
org.apache.hadoop.hive.ql.exec.Utils.removeTempOrDuplicateFiles) when
collecting the final outputs
{code}
