Thanks. > Get with closest_row_before on "hbase:meta" can return empty Cell during region merge/split > ------------------------------------------------------------------------------------------- > > Key: HBASE-18066 > URL: https://issues.apache.org/jira/browse/HBASE-18066 > Project: HBase > Issue Type: Bug > Components: hbase, regionserver > Affects Versions: 1.3.1 > Environment: Linux (16.04.2), MacOS 10.11.6. > Standalone and distributed HBase setup. > Reporter: Andrey Elenskiy > Assignee: Zheng Hu > Attachments: HBASE-18066.branch-1.1.v1.patch, HBASE-18066.branch-1.3.v1.patch, HBASE-18066.branch-1.v1.patch, HBASE-18066.branch-1.v2.patch, HBASE-18066.branch-1.v3.patch, TestGetWithClosestRowBeforeWhenSplit.java > > > During region split/merge there's a brief period of time where doing a "Get" with "closest_row_before=true" on "hbase:meta" may return empty "GetResponse.result.cell" field even though parent, splitA and splitB regions are all in "hbase:meta". Both gohbase (https://github.com/tsuna/gohbase) and AsyncHBase (https://github.com/OpenTSDB/asynchbase) interprets this as "TableDoesNotExist", which is returned to the client. > Here's a gist that reproduces this problem: https://gist.github.com/Timoha/c7a236b768be9220e85e53e1ca53bf96. Note that you have to use older HTable client (I used 1.2.4) as current versions ignore `Get.setClosestRowBefore(bool)` option. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
