Hello
I have a cluster with:
* three nodes: rb01, rb02 and rb03
* three topics: rb_event, rb_monitor, rb_flow
* three partitions per topic
* replicas 2
The current status is:
Topic Partition Leader Replicas In-Sync replicas
-------------------------------------------------------------------------------
rb_event 0 2 2,1 2,0
1 2 1,2 2,0
2 2 1,2 2
-------------------------------------------------------------------------------
rb_flow 0 2 1,2 2,0
1 2 2,0 2,0
2 0 0,1 0,1
-------------------------------------------------------------------------------
rb_monitor 0 2 1,2 2
1 2 2,1 2,0
2 0 0,2 2,0
-------------------------------------------------------------------------------
I see something strange. For example:
* rb_event -> partition 0 has replicas 2,1 but In sync replicas are 2,0
-> that is normal ???
And the worst it when I try to reassign propertly the partitions:
The kafka-reassign-partitions.sh tries to write
to /admin/reassign_partitions the following:
{"partitions":[{"topic":"rb_event","partition":0,"replicas":[0,1]},{"topic":"rb_event","partition":1,"replicas":[1,2]},{"topic":"rb_event","partition":2,"replicas":[2,0]},{"topic":"rb_monitor","partition":0,"replicas":[2,0]},{"topic":"rb_monitor","partition":1,"replicas":[0,1]},{"topic":"rb_monitor","partition":2,"replicas":[1,2]}]}
When I access to zookeeper I do see:
[zk: rb02:2181,rb01:2181,rb03:2181(CONNECTED) 3] get
/admin/reassign_partitions
{ "partitions":[ { "partition":2, "replicas":[ 1, 2 ], "topic":"rb_monitor"
}, { "partition":0, "replicas":[ 2, 0 ], "topic":"rb_monitor" }, {
"partition":1, "replicas":[ 0, 1 ], "topic":"rb_monitor" }, {
"partition":0, "replicas":[ 0, 1 ], "topic":"rb_event" }, { "partition":2,
"replicas":[ 2, 0 ], "topic":"rb_event" } ], "version":1 }
And keep there for ever
What can I do ?
Thanks
Pablo
