Where to findout zookeeper.log

[#1]

There is no zookeeper.log file in my culster.

[root@insightcluster130 zookeeper]# ls -lart
total 4
drwxr-xr-x.  2 zookeeper hadoop   61 Sep 21 21:32 .
drwxr-xr-x. 28 root      root   4096 Dec 18 03:45 ..
-rw-r--r--.  1 zookeeper hadoop    0 Dec 21 17:29 zookeeper-zookeeper-server-insightcluster130.out
[root@insightcluster130 zookeeper]# pwd
/var/log/zookeeper
[root@insightcluster130 zookeeper]# 

Don't know why

[#2]

by default zookeeper is configured with console appender so that all zk logs are directed to out file, you can configure zk with Rolling file or DRFA to redirect the output to log file.

[#3]

zookeeper server redirects the stderr and stdout to zookeeper.out

As mentioned above you can use ROLLINGFILE which is sent to zookeeper.log

@Rajkumar Singh @Namit Maheshwari But my

zookeeper-zookeeper-server-insightcluster130.out

always in size 0.

[#5]

@Huahua Wei could you please share the output of the command

lsof -p <pid of zookeeper> |grep log

lsof -p <pid of zookeeper> | grep out

@Huahua Wei lsof output suggest that your zk log location is /var/log/zookeeper/zookeeper-zookeeper-server-insightcluster132.out
