https://community.cloudera.com/t5/Support-Questions/failure-in-starting-zookeeper-service/m-p/127410#M90125 <P>Dear <A href="https://community.hortonworks.com/users/102/nmaheshwari.html">Namit Maheshwari</A> I deleted the directory /usr/hdp/2.5.0.0-1245/zookeeper/conf, but the ambari re-created it and all the contents that were in it previously. </P><P>Zookeeper client starts successfully and it contains the same contents of that directory in client hosts. For example, on the host "n4", which is client zookeeper, I get this:</P><PRE>[root@n4 ~]# ls -l /usr/hdp/2.5.0.0-1245/zookeeper/conf total 16 -rw-r--r-- 1 zookeeper hadoop 548 Feb 9 01:22 configuration.xsl -rw-r--r-- 1 zookeeper hadoop 2444 Feb 9 01:22 log4j.properties -rw-r--r-- 1 zookeeper hadoop 1048 Feb 9 01:22 zoo.cfg -rw-r--r-- 1 zookeeper hadoop 310 Feb 9 01:22 zookeeper-env.sh -rw-r--r-- 1 zookeeper hadoop 0 Feb 9 01:22 zoo_sample.cfg </PRE> Mon, 27 Feb 2017 09:09:26 GMT shadi 2017-02-27T09:09:26Z
