Review request for Ambari, Andrew Onischuk and Dmitro Lisnichenko.
Bugs: AMBARI-22361
https://issues.apache.org/jira/browse/AMBARI-22361
Repository: ambari
Description
-------
In the ambari console, a critical alert gets reported for the NameNode Web UI
due to mixed cases in hostname
Error at hand:
Connection failed to http://vz-sl-upupup-8724-hadoop-mgr-1:0 (<urlopen error
[Errno 111] Connection refused>)
Issue:
While in HA mode the hdfs-site property
dfs.namenode.http-address.{{ha-nameservice}}.{{nn_id}}
may have upper case parts, which prevents matching the hostname.
The matching should be case insensitive and so both will be
converted to lower case before the matching is performed.
Fix:
lower case before doing the comparison
(samilar resolution as in https://issues.apache.org/jira/browse/AMBARI-19282)
Diffs
-----
ambari-agent/src/main/python/ambari_agent/alerts/base_alert.py 05f80234d0
Diff: https://reviews.apache.org/r/63558/diff/1/
Testing
-------
Verified the ambari console doesn't report the critical alert any more.
(the ambari console reports http return code 200 when testing the NameNode Web
UI access).
Thanks,
