Subject [jira] [Commented] (INFRA-10150) HBase Jenkins builds fail due to 'unable to create new native thread' error
Date Wed, 19 Aug 2015 21:01:46 GMT

    [ https://issues.apache.org/jira/browse/INFRA-10150?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14703733#comment-14703733
] 

Ted Yu commented on INFRA-10150:
--------------------------------

Do you remember roughly how many were killed on H3 and H4 ?
I wonder if the following parameters differ on the hosts:
{code}
[root@cn012 ~]# sysctl fs.file-max
fs.file-max = 13131077
[root@cn012 ~]# sysctl kernel.threads-max
kernel.threads-max = 2064126
{code}
See https://support.adeptia.com/entries/21540822-Steps-to-resolve-unable-to-create-new-native-thread-issue-on-Linux-

Thanks
