Daniel Pinyol commented on CASSANDRA-6788:
------------------------------------------
With both Cassandra 1.2.19 and 2.2.5 (which should contain the patch) I can
experience a similar problem, with both OSX and linux. I use thrift with
scale7-pelops 1.3-1.1.x. This is my pseudocode. I use dynamic columns.
{noformat}
for(column=1..1000)
{
for(value=1..25)
{
write("CF1", "key1", column, writtenValue);
readValue = read("CF1", "key1", column);
some times here readValue!=writtenValue. Once this happens, sleeping and
reading again does not help
}
}
{noformat}
The only alternative ways to avoid the problem are:
* inserting a sleep (any duration) right after the put.
* replacing thrift with CQL
* This sounds crazy, but each value contains the previous one as prefix (1, 12,
123, 1234...) it never fails.

> There's a race condition in CustomTThreadPoolServer that can cause the thrift
> server to silently stop listening for connections.
> It happens when the executor service throws a RejectedExecutionException,
> which is not caught.
>
> Silent in the sense that OpsCenter doesn't notice any problem since JMX is
> still running fine.
