@HarshJ Thanks for inputs. I checked heap charts on jobtracker instance and it's hitting the maximum heap value frequently and then reducing to little less value. Also, there has not been any change/increase in load. I checked the jobtracker logs but couldn't find any pauses as logging is not enabled for GC. Can you please let me know what are the history retention configurations of jobtracker? Can you please suggest me how to identify the reason behind the GC taking significant time? Thanks, Priya

Hi,
We are getting warning (concerning) messages for mapreduce1 jobtracker frequently on our Cloudera CDH 5.9 cluster. Currently java heap size of jobtracker is 4.11GB and it's 14-node cluster.
Below is the warning message that appears regarding the garbage collection.
Test of whether this role spends too much time in garbage collection.
Concerning:Average time spent in garbage collection was 20.6 seconds(34.28%)per minute over the previous 5 minute(s).Warning threshold:30.00%
Can someone please help me to get rid of the issue?
Thanks,
Priya

@Harsh J, Thanks for quick reply. I thought the ouptut of fsck command includes replica multiplier and gives final total block count. Thanks for the clarification. I checked Datanodes page on namenode WebUI and block count for each datanode is more than threshold value. Thanks, Priya

@Harsh J Thanks for the reply. I am checking the block count by using the command hdfs fsck path and referring to total blocks column in the output. Please suggest whether this is the right way or not. Thanks, Priya

@saranvisa, It was b>a earlier. I removed files using command line and block count is below threshold value. However it's not reflected in cloudera manager console. Please suggest. Thanks,

Hello All, We have CDH5.9.2 hadoop 13-node cluster and from one week, I am exeperiencing block count concerning warning notification in cloudera manager for all 6 datanodes. We have multitenancy implemented in our cluster. So I deleted the older files via hdfs command line and block count is below the threshold value. But still the block count concerning warning appears in the cloudera manager. Please suggest. Thanks, Priya
