Hi All, We have plan to change rack awarness our production server. At the moment our production server rack contain 14 hadoop node using replication 2 . we want to move those rack to another data center room and decrease from 14 to 10 hadoop node per rack, but we worry about distribution and replication existing data. Do we need restart datanode service and rebalance the data after change configuration and Is there any guidance or documentation related changing rack awarness configuration? Regards, i9um0

I must confirm to our hadoop admin which method that they us when installing cloudera manager. but our question what are the differences about the embedded database and the other ? is it just only separate machine or it can be install on same machine with enough capacity to cater the load. regards, -mugi-

Hi, we still using postgresql CM DB and already check to etc/cloudera-scm-server/db.mgmt.properties all connection ok. All Cloudera manager management services running well and never any trouble, command "psql -h localhost -U cloudera-scm -p 7432" executed with no error it mean with we can connect using cloudera-scm to postgresql through psql. regards, -mugi-

Hi Gautam, Thank's for quick response. As i told you before we have problem with HDFS block, currently our HDFS block reach to 58 millions with storage occupied equal to 500TB it's not quite ideal. NN memory capacity is about 64GB and we set 32GB for NN heap. Last time we change dfs.namenode.checkpoint.txns at the same time with dfs.image.compress from default 44K to 1000K because, we thought when the system often do checkpoint thats lead namenode service become bad as CM report through email. About your question JT pause only began when you turned on compression of fsimage?. We not sure about that cause the mapreduce pause never like now until 10 minutes, whether it happens or not we do not notice. Does only increase NN heap memory or there are other alternatives that we can tune related with hadoop parameters will reduce load HDFS and will bring back mapreduce to normal during checkpoint ? regards, i9um0

Hi Gautam, roughly about 10-15 minutes, last time we change configuration of dfs.image.compress from false to true cause we have problem with FSImage size that growing fast. did it affect with Mapred process ? . our team will run jstack and inform you later on. regards, i9um0
