Hello, I am using Cloudera v5.4.8 1 NN & 5 Data Node Hbase Thrift & Hbase Master are on NN1. I am seeing below warning in Thrift Server Logs: [After 10 to 15 days interval] WARN org.apache.hadoop.hbase.thrift.TBoundedThreadPoolServer: Queue is full, closing connection from x.x.x.x 1. How to check current active connections in Hbase via Thrift ? Currently I check for ESTABLISHED connections at OS on port 9090 ? 2 . How to avoid above issue ? 3. Also, as per https://hbase.apache.org/0.94/xref/org/apache/hadoop/hbase/thrift/TBoundedThreadPoolServer.html Only when the queue overflows, new threads are added, up to hbase.thrift.maxQueuedRequests threads Can anyone explain this with example ?

Hello All, I am quite new to CDH. I have come across a CDH v5.4.8 Cluster, for a POC setup consisting of 6 Nodes. 1 Name Node & 5 Data Nodes. I know 6 nodes are not enough, but what will be best role assignment and distribution for the given cluster for POC. Services used will be will be Spark , Solr & HBase. Also how can i test configure & test HA for the same services ? Secondly , Requirement is for making Cloudera Manager HA. I have gone through documentation of Cloudera for the same. It says that, 1. Embedded PostgreSQL is not supported. 2. Cloudera Manager Server & Services should not be on same host. I have all of it installed on same Name Node. How can i move it from the existing Name Node to a new server ? If any details required let me know. I know above scenario is a bit mess but challange herr is to reorganisation of cluster. Thanks, Dark
