Ed Schmed commented on ZOOKEEPER-1927:
--------------------------------------
both
-bash-3.2$ grep "^[ \t\r\n\v\f]*dataDir"
/fuse/zookeeper-3.4.6/bin/../conf/zoo.cfg
dataDir=/fuse/zookeeper_data
and
-bash-3.2$ grep "^[ \s]*dataDir" /fuse/zookeeper-3.4.6/bin/../conf/zoo.cfg
dataDir=/fuse/zookeeper_data
work with the ancient built in solaris grep with no leading space, a single
leading space, and many leading spaces.
However... neither work if their is a tab character inserted before the dataDir
variable....
They are supposed to recognize tab from what i've read, but they are not
working.
I will see if I can play around and find any thing else that does work, unless
you have some other suggestions?
Thanks,
Ed

> Key: ZOOKEEPER-1927
> URL: https://issues.apache.org/jira/browse/ZOOKEEPER-1927
> Project: ZooKeeper
> Issue Type: Bug
> Components: scripts
> Affects Versions: 3.4.6
> Environment: Solaris 5.10
> Reporter: Ed Schmed
>
> Fails to write PID file with a permissions error, because the startup script
> fails to read the dataDir variable from zoo.cfg, and then tries to use the
> drive root ( / ) as the data dir.
> Tracked the problem down to line 84 of zkServer.sh:
> ZOO_DATADIR="$(grep "^[[:space:]]*dataDir" "$ZOOCFG" | sed -e 's/.*=//')"
> If i run just that line and point it right at the config file, ZOO_DATADIR is
> empty.
> If I remove [[:space:]]* from the grep:
> ZOO_DATADIR="$(grep "^dataDir" "$ZOOCFG" | sed -e 's/.*=//')"
> Then it works fine. (If I also make the same change on line 164 and 169)
> My regex skills are pretty bad, so I'm afraid to comment on why [[space]]*
> needs to be in there?
