Subject [jira] [Commented] (HBASE-14317) Stuck FSHLog: bad disk (HDFS-8960) and can't roll WAL
Date Sun, 06 Sep 2015 04:01:46 GMT

    [ https://issues.apache.org/jira/browse/HBASE-14317?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14732181#comment-14732181

stack commented on HBASE-14317:
-------------------------------

Hanging tests this time are:
kalashnikov:hbase.git.commit stack$ python ./dev-support/findHangingTests.py  https://builds.apache.org/job/PreCommit-HBASE-Build/15442//consoleText
Fetching the console output from the URL
Printing hanging tests
Hanging test : org.apache.hadoop.hbase.security.access.TestWithDisabledAuthorization
Hanging test : org.apache.hadoop.hbase.security.access.TestAccessController2
Hanging test : org.apache.hadoop.hbase.client.TestHCM
Hanging test : org.apache.hadoop.hbase.security.access.TestAccessControlFilter
Printing Failing tests

Some items in common. Let me retry and look at what happens local. I've been trying to run
all tests locally too. The two last runs seem to be missing TestWithDisabledAuthorization,
TestAccessController2, and TestAccessControlFilter. The other tests all pass for me. Let me
rerun and try these tests locally too.

> hbase-1.1.1 and hadoop-2.7.1
> We try to roll logs because can't append (See HDFS-8960) but we get stuck. See attached
thread dump and associated log. What is interesting is that syncers are waiting to take syncs
to run and at same time we want to flush so we are waiting on a safe point but there seems
to be nothing in our ring buffer; did we go to roll log and not add safe point sync to clear
out ringbuffer?
> Needs a bit of study. Try to reproduce.
