Hi All - we're using Apache Solr Cloud 5.2.1, with an HDFS system that is
86% full. Some of the datanodes in the HDFS cluster are more close to
being full than other nodes. We're getting messages about "Error adding
log" from the index process, which I **think** is related to datanodes
being full.
Is that the case? Even though HDFS still has room available?
Upon restart of Solr Cloud, we see messages such as:
ERROR - 2016-01-28 22:15:27.594; [ UNCLASS]

Some shards in the cluster can take hours to come back up. Any ideas? It
appears to wait 900 seconds for each of the tlog files. When there are 60+
files - this takes a long time!
Thank you!
