Phoenix creates 224 regions for SYSTEM.SEQUENCE and then it kills all region servers

Hi,

 

I am using the Cloudera Manager on a six-node cluster (master: aaa, the others: node[1-5]). It runs CDH 5.5.2 and consists of HBase, HDFS and ZooKeeper. I downloaded, distributed and enabled the Phoenix Parcel 4.5.2-1.clabs_phoenix1.2.0.p0.774

 

On the HBase-Web-UI:

* Region Servers: my five nodes, two have Num. Regions = 1 (hbase:namespace and hbase:meta), the others have 0

 

Now I start Phoenix:

* cd /etc/hbase/conf

* /usr/bin/phoenix-sqlline.py localhost:2181:/hbase

 

On the HBase-Web-UI:

* SYSTEM.CATALOG is created

* SYSTEM.SEQUENCE is created and has 12 regions

* Browser reload (F5): Now, SYSTEM.SEQUENCE has 200 region

* When SYSTEM.SEQUENCE has 224 regions, all Region Servers are dead.

* Regions in transition. Red entry: SYSTEM.SEQUENCE,,1455886910318.84b30d86ec2535f7ff514b9eca1a62ff. state=FAILED_OPEN, ts=Fri Feb 19 14:01:52 CET 2016 (34s ago), server=aaa,60020,1455886812045

 

I also tried to use the Phoenix tar instead of the Cloudera parcel. Exactly the same behavior.

 

Thanks for every kind of help!

 

Johannes

Same problem. Had you got some workaround ?

Yes, I asked the Phoenix mailing list. I had to set phoenix.sequence.saltBuckets to 0.
