Re: IllegalArgumentException excpetion : Path cannot be null
The client (solr in this case) is passing a null path to the
ZooKeeper.getChildren(path, ... ) call.
java.lang.IllegalArgumentException: Path cannot be null
at
org.apache.zookeeper.common.PathUtils.validatePath(PathUtils.java:45)
at
org.apache.zookeeper.ZooKeeper.getChildren(zookeeper:ZooKeeper.java):1196)
at
org.apache.solr.common.cloud.SolrZkClient.getChildren(SolrZkClient.java:200)
I'm afraid you'll have to work with the solr team to determine the cause of
this.
