Hi, I have a SolrCloud (on HDFS) of 52 nodes. I have 3 collections each with 50 shards and maxShards per node for every collection is 1.
I am having problem restarting a solr shard for a collection. When I restart, there is always a particular shard of a particular collection that remains down. The 2 shards on the same host for the rest of the collections are up and running. Before restarting, I delete all the write.lock files from the data dir. But every time I restart I get the same exception. index dir yyy of core xxx is already locked. The most likely cause is another Solr server (or another solr core in this server) also configured to use this directory; other possible causes may be specific to lockType: hdfs Thanks!
