----------------------------------------
Summary: [HDP 2.3] hadoop-env advance config has Java Heap size
bug
Key: AMBARI-15068
URL: https://issues.apache.org/jira/browse/AMBARI-15068
Project: Ambari
Issue Type: Bug
Components: ambari-server
Affects Versions: stacks
Reporter: Himanshu Sharma
With Ambari-2.2, there is an issue with HDP-2.3 whereby the advanced hadoop-env
default properties have few errant values like :
"dtnode_heapsize" : "1024"
"namenode_heapsize" : "1024"
Instead of above it should be the following as in HDP-2.2 :
"dtnode_heapsize" : "1024m"
"namenode_heapsize" : "1024m"
Note the missing "m" because of which the default heapsize for DataNodes and
NameNodes is getting initialized as 1KB instead of 1GB. This causes, respective
JVMs unable to startup and cluster initialization fails.
I initially thought that the bug would be related to Ambari. But this is
related to HDP-2.3 as its not visible in HDP-2.2.
