Subject [jira] [Commented] (TEPHRA-300) Tephra coprocessors do not close passed scanner
Date Fri, 24 May 2019 21:08:00 GMT

    [ https://issues.apache.org/jira/browse/TEPHRA-300?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16847894#comment-16847894
] 

Lars Hofhansl commented on TEPHRA-300:
--------------------------------------

-v2 should be committable. Fixed for all versions of HBase. 2.0 does *not* need this. HBase
has improved its APIs there and it no longer need to produce a completely new scanner.
I used try-with-resource instead of
{code:java}
try { if (s != null) { s.close() } } catch (IOException ignore) {}{code}
as I think that is more concise.

> With HBase 1.5+ this leads to incorrect reference counting on opened HFile resulting
in those to never get archived.
