Guozhang Wang commented on KAFKA-4540:
--------------------------------------
Is this already resolved as part of
https://issues.apache.org/jira/browse/KAFKA-4509? In the patch we reorder the
operations to first close all the suspended tasks and then try to create new
tasks.
> Suspended tasks that are not assigned to the StreamThread need to be closed
> before new active and standby tasks are created

> Project: Kafka
> Issue Type: Bug
> Components: streams
> Affects Versions: 0.10.2.0
> Reporter: Damian Guy
> Assignee: Damian Guy
> Fix For: 0.10.2.0

>
> When partition assignment happens we first try and add the active tasks and
> then add the standby tasks. The problem with this is that a new active task
> might already be an existing suspended standby task. if this is the case then
> when the active task initialises it will throw an exception from RocksDB:
> {{Caused by: org.rocksdb.RocksDBException: IO error: lock
> /tmp/kafka-streams-7071/kafka-music-charts/1_1/rocksdb/all-songs/LOCK: No
> locks available}}
> We need to make sure we have removed an closed any no-longer assigned
> Suspended tasks before creating new tasks.
