Subject [jira] [Commented] (HADOOP-16276) Fix jsvc startup command in hadoop-functions.sh due to jsvc >= 1.0.11 changed default current working directory
Date Wed, 01 May 2019 21:19:00 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-16276?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16831260#comment-16831260

Hrishikesh Gadre commented on HADOOP-16276:
-------------------------------------------

[~smeng] thanks for the patch. Can we allow user to configure the directory to be used for
cwd parameter? That will probably simplify the fix on the management software side (because
we can just configure that path at one place instead changing config generators at multiple
places). What do you think?

> 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.
