Subject [jira] [Updated] (HADOOP-16276) Fix jsvc startup command in hadoop-functions.sh due to jsvc >= 1.0.11 changed default current working directory
Date Thu, 02 May 2019 17:33:00 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-16276?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Siyao Meng updated HADOOP-16276:
--------------------------------
    Attachment: HADOOP-16276.003.patch
        Status: Patch Available  (was: In Progress)

[~hgadre] Sure. In patch 003. I've added an external environment variable JSVC_EXTRA_HADOOP_DAEMON_OPTS
that allows the user to add jsvc options to the command line. When JSVC_EXTRA_HADOOP_DAEMON_OPTS
is NOT set, cwd option will be automatically added if jsvc version < 1.0.11; when JSVC_EXTRA_HADOOP_DAEMON_OPTS
is set, cwd option will NOT be added automatically and the users are responsible to set "-cwd
/path/to/dir" they need.

> In CDH6, when we bump jsvc from 1.0.10 to 1.1.0 we hit *KerberosAuthException: failure
to login / LoginException: Unable to obtain password from user* due to DAEMON-264 and our

> *dfs.nfs.keytab.file* config uses a relative path. I will probably file another jira
to issue a warning like *hdfs.keytab not found* before KerberosAuthException in this case.
> The solution is to add *-cwd $(pwd)* in function hadoop_start_secure_daemon in hadoop-functions.sh
but I will have to consider the compatibility with older jsvc versions <= 1.0.10. Will
post the patch after I tested it.
> Thanks [~tlipcon] for finding the root cause.
