Daniel Templeton commented on HADOOP-16276:
-------------------------------------------
I actually like the auto-detect with an optional override. We try to do the
right thing but let the user have ultimate control. The override is important
so that management software can control where the keytabs live. I think the
auto-detect is important to maintain backwards compatibility. If someone not
using a vendor's tool deploys 3.3 without the auto-detect and without making
the right changes, their deploy will break.
That said, I think the auto-detect is unnecessarily brittle. Why are we
looking for the n-3rd line instead of grepping for "cwd"?

> Project: Hadoop Common
> Issue Type: Bug
> Components: scripts
> Affects Versions: 3.2.0, 3.1.2
> Reporter: Siyao Meng
> Assignee: Siyao Meng
> Priority: Major
> Attachments: HADOOP-16276.001.patch, HADOOP-16276.002.patch,

> 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.
