Hi team, I have just started to learn kafka following https://kafka.apache.org/quickstart
When I have started my zookeeper server and kafka server, I got a few exceptions in the log which are all "KepperExcetion". Even when i created a topic with name test I got the same exception. Can anyone throw some light on the same. Here is an excerpt from log [2019-05-13 11:01:48,010] INFO Got user-level KeeperException when processing sessionid:0x1000081a14b0000 type:create cxid:0x1 zxid:0x1f txntype:-1 reqpath:n/a Error Path:/consumers Error:KeeperErrorCode = NodeExists for /consumers (org.apache.zookeeper.server.PrepRequestProcessor) [2019-05-13 11:01:48,073] INFO Got user-level KeeperException when processing sessionid:0x1000081a14b0000 type:create cxid:0x2 zxid:0x20 txntype:-1 reqpath:n/a Error Path:/brokers/ids Error:KeeperErrorCode = NodeExists for /brokers/ids (org.apache.zookeeper.server.PrepRequestProcessor) [2019-05-13 11:01:48,122] INFO Got user-level KeeperException when processing sessionid:0x1000081a14b0000 type:create cxid:0x3 zxid:0x21 txntype:-1 reqpath:n/a Error Path:/brokers/topics Error:KeeperErrorCode = NodeExists for /brokers/topics (org.apache.zookeeper.server.PrepRequestProcessor) [2019-05-13 11:01:48,161] INFO Got user-level KeeperException when processing sessionid:0x1000081a14b0000 type:create cxid:0x4 zxid:0x22 txntype:-1 reqpath:n/a Error Path:/config/changes Error:KeeperErrorCode = NodeExists for /config/changes (org.apache.zookeeper.server.PrepRequestProcessor) [2019-05-13 11:01:48,190] INFO Got user-level KeeperException when processing sessionid:0x1000081a14b0000 type:create cxid:0x5 zxid:0x23 txntype:-1 reqpath:n/a Error Path:/admin/delete_topics Error:KeeperErrorCode = NodeExists for /admin/delete_topics (org.apache.zookeeper.server.PrepRequestProcessor) [2019-05-13 11:01:48,215] INFO Got user-level KeeperException when processing sessionid:0x1000081a14b0000 type:create cxid:0x6 zxid:0x24 txntype:-1 reqpath:n/a Error Path:/brokers/seqid Error:KeeperErrorCode = NodeExists for /brokers/seqid (org.apache.zookeeper.server.PrepRequestProcessor) [2019-05-13 11:01:48,245] INFO Got user-level KeeperException when processing sessionid:0x1000081a14b0000 type:create cxid:0x7 zxid:0x25 txntype:-1 reqpath:n/a Error Path:/isr_change_notification Error:KeeperErrorCode = NodeExists for /isr_change_notification (org.apache.zookeeper.server.PrepRequestProcessor) [2019-05-13 11:01:48,270] INFO Got user-level KeeperException when processing sessionid:0x1000081a14b0000 type:create cxid:0x8 zxid:0x26 txntype:-1 reqpath:n/a Error Path:/latest_producer_id_block Error:KeeperErrorCode = NodeExists for /latest_producer_id_block (org.apache.zookeeper.server.PrepRequestProcessor) [2019-05-13 11:01:48,300] INFO Got user-level KeeperException when processing sessionid:0x1000081a14b0000 type:create cxid:0x9 zxid:0x27 txntype:-1 reqpath:n/a Error Path:/log_dir_event_notification Error:KeeperErrorCode = NodeExists for /log_dir_event_notification (org.apache.zookeeper.server.PrepRequestProcessor) [2019-05-13 11:01:48,337] INFO Got user-level KeeperException when processing sessionid:0x1000081a14b0000 type:create cxid:0xa zxid:0x28 txntype:-1 reqpath:n/a Error Path:/config/topics Error:KeeperErrorCode = NodeExists for /config/topics (org.apache.zookeeper.server.PrepRequestProcessor) [2019-05-13 11:01:48,366] INFO Got user-level KeeperException when processing sessionid:0x1000081a14b0000 type:create cxid:0xb zxid:0x29 txntype:-1 reqpath:n/a Error Path:/config/clients Error:KeeperErrorCode = NodeExists for /config/clients (org.apache.zookeeper.server.PrepRequestProcessor) [2019-05-13 11:01:48,393] INFO Got user-level KeeperException when processing sessionid:0x1000081a14b0000 type:create cxid:0xc zxid:0x2a txntype:-1 reqpath:n/a Error Path:/config/users Error:KeeperErrorCode = NodeExists for /config/users (org.apache.zookeeper.server.PrepRequestProcessor) [2019-05-13 11:01:48,422] INFO Got user-level KeeperException when processing sessionid:0x1000081a14b0000 type:create cxid:0xd zxid:0x2b txntype:-1 reqpath:n/a Error Path:/config/brokers Error:KeeperErrorCode = NodeExists for /config/brokers (org.apache.zookeeper.server.PrepRequestProcessor) Regards Gagan
