Subject [jira] [Updated] (HIVE-17833) Publish split generation counters
Date Thu, 19 Oct 2017 01:14:00 GMT


Prasanth Jayachandran updated HIVE-17833:
    Attachment: HIVE-17833.2.patch

Addressed review comments. Removed pom.xml changes. Will update it once tez makes a release
until then this patch can't be committed anyway. 

2 counters one for #files that will be read by input and other for #directories (did not call
it partitions as we are not checking with partition spec). #directories comes from jobConf
via mapred.input.dir. So only #files has to make sure the path in split is a file. There can
be OrcSplit with delta directory which don't account for in any of these counters (expensive
to do list status on each delta directories here).
