Subject [jira] [Commented] (HBASE-16886) hbase-client: scanner with reversed=true and small=true gets no result
Date Thu, 27 Oct 2016 07:27:58 GMT

    [ https://issues.apache.org/jira/browse/HBASE-16886?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15611021#comment-15611021

huzheng commented on HBASE-16886:

Hi, [~tedyu] all unit test seems passed.  

TestMultiTableSnapshotInputFormat  test  is OK in my desktop,  and the failed cause of Hadoop
QA is :

java.io.IOException: Unable to create region directory: /tmp/scantest2_snapshot__043a17e4-3572-4aea-9bcb-330edecd5a39/data/default/scantest2/1bbfd104c261fc1d4677d66728299f51

after checked the code files,  it seems nothing to do with this patch.   but this ut case
is unstable . Any advise ?
