Subject [jira] [Commented] (CASSANDRA-10291) Bootstrap hangs on adding new node
Date Thu, 10 Sep 2015 22:17:45 GMT


Ara Sadoyan commented on CASSANDRA-10291:

This cluster is running for almost a year and there were no problems in 2.1 .
Problem appeared after I have upgraded to 2.2. Today I did bootstrap again and failed same
way, but there was nothing in logs.
Regarding network. These servers are directly connected to gbit switch .
I have lowered down stream speed so commulative traffic to bootstrapping node was about 700
mbit, just to ensure that I do not have bandwidth problem. So i guess this is a bug.

> Adding new node in heavy loaded environment freeze bootstrap. No errors are reported
in log files.  Some of other other nodes throws "String didn't validate" error, but I;m not
sure that this is related. 
> After restarting node it start bootstrap again and hangs after some time .

> This happens only if there is significant amount of data. I have 1.5 TB per node on 13
node cluster, we use STCS compaction strategy and flat network topology .
