HBase Thrift - Queue is full

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 ?

Hi @TheDarkWizard, I moved your post to the Hbase forum so you may get attention from the appropriate folks.
