RESOLVED ISSUES

 

* Bug ID 240177

  The Hadoop Distributed File System (HDFS) rename command did not manage file

  handles correctly and might have caused data unavailability with

  STATUS_TOO_MANY_OPEN_FILES error.

 

* Bug ID 236286

  If a OneFS cluster had the Hadoop Distributed File System (HDFS) configured

  for Kerberos authentication, WebHDFS requests over curl might have failed to

  follow a redirect request.

 

 

 

 

Other Known Issues

1. Host Registrations fails on RHEL 7 hosts with openssl issues

 

Modify the ambari-agent.ini file:

/etc/ambari-agent/conf/ambari-agent.ini

 

[security]

force_https_protocol=PROTOCOL_TLSv1_2

 

 

Restart the ambari-server and all ambari-agents



2. Installs fail when using Private Repos with Ambari

Isilon presents itself as a Centos06 host and Ambari expects to see the centos6 repos, without internet access to the public repos installs will fail if a local Centos6 repo is not available and accessible <KB coming on this issue shortly>
