Elliott Clark resolved HBASE-8619.
----------------------------------
Resolution: Not a Problem
This got better somewhere along the way
> [HBase Client]: Improve client to retry if master is down when requesting
> getHTableDescriptor
> ---------------------------------------------------------------------------------------------
>
> Key: HBASE-8619
> URL: https://issues.apache.org/jira/browse/HBASE-8619
> Project: HBase
> Issue Type: Bug
> Components: Client
> Affects Versions: 0.94.8
> Reporter: Aleksandr Shulman
> Assignee: Elliott Clark
> Priority: Minor
>
> In our rolling upgrade testing, running ImportTsv failed in the job
> submission phase when the master was down. This was when the master was
> failing over to the backup master. In this case, a retry would have been
> helpful and made sure that the job would get submitted.
> A good solution would be to refresh the master information before placing the
> call to getHTableDescriptor.
> Command:
> {code} sudo -u hbase hbase org.apache.hadoop.hbase.mapreduce.ImportTsv
> -Dimporttsv.columns=HBASE_ROW_KEY,c1,c2,c3
> -Dimporttsv.bulk.output=/user/hbase/storeFiles2_2/import2_table1369439156
> import2_table1369439156 /user/hbase/tsv2{code}
> Here is the stack trace:
