Siyao Meng commented on HADOOP-16276:
-------------------------------------
Tested on a CDH cluster with the modified hadoop-functions.sh script. It works
as intended:
when HADOOP_DAEMON_JSVC_EXTRA_OPTS is already set:
{code}
DEBUG: HADOOP_DAEMON_JSVC_EXTRA_OPTS is set. Ignoring jsvc -cwd option
detection and addition.
{code}
when HADOOP_DAEMON_JSVC_EXTRA_OPTS is *not* set, with jsvc 1.1.0 (has -cwd
option):
{code}
DEBUG: Your jsvc supports -cwd option. Adding option '-cwd .'. See HADOOP-16276
for details.
{code}
when HADOOP_DAEMON_JSVC_EXTRA_OPTS is *not* set, with jsvc 1.0.10 (doesn't have
-cwd option):
{code}
DEBUG: Your jsvc doesn't support -cwd option. No need to add option '-cwd .'.
See HADOOP-16276 for details.
{code}
> Fix jsvc startup command in hadoop-functions.sh due to jsvc >= 1.0.11 changed
> default current working directory

> 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,
> HADOOP-16276.003.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.
