Review request for Ambari, Di Li, Jonathan Hurley, Sumit Mohanty, Sid Wagle,
and Tim Thorpe.
Bugs: AMBARI-21528
https://issues.apache.org/jira/browse/AMBARI-21528
Repository: ambari
Description
-------
Repro Steps:
* Installed BI 4.2.0 cluster on IBM Ambari 2.2.2 with Zookeeper
* Upgraded Ambari to 2.5.2.0-146
* Registered HDP 2.6.2.0 repo, installed packages
* Ran service checks
* Started Express Upgrade
Result: _Service Check ZooKeeper_ step failed with {{KeeperErrorCode =
ConnectionLoss for /zk_smoketest}}
This was caused by Zookeeper dying immediately during restart:
```
Error occurred during initialization of VM
Too small initial heap
```
Before EU
```
export JAVA_HOME=/usr/jdk64/java-1.8.0-openjdk-1.8.0.77-0.b03.el7_2.x86_64
export ZOOKEEPER_HOME=/usr/iop/current/zookeeper-server
export ZOO_LOG_DIR=/var/log/zookeeper
export ZOOPIDFILE=/var/run/zookeeper/zookeeper_server.pid
export SERVER_JVMFLAGS=-Xmx1024m
export JAVA=$JAVA_HOME/bin/java
export CLASSPATH=$CLASSPATH:/usr/share/zookeeper/*
```
After EU
```
export JAVA_HOME=/usr/jdk64/java-1.8.0-openjdk-1.8.0.77-0.b03.el7_2.x86_64
export ZOOKEEPER_HOME=/usr/hdp/current/zookeeper-client
export ZOO_LOG_DIR=/var/log/zookeeper
export ZOOPIDFILE=/var/run/zookeeper/zookeeper_server.pid
export SERVER_JVMFLAGS=-Xmx1024
export JAVA=$JAVA_HOME/bin/java
```
Note missing "m" in memory setting.
zookeeper-env template contains,
```
export SERVER_JVMFLAGS={{zk_server_heapsize}}
```
In this cluster, zookeeper-env contains,
zk_server_heapsize: "1024"
While the params_linux.py file has some inconsistencies with appending the
letter "m".
```
zk_server_heapsize_value =
str(default('configurations/zookeeper-env/zk_server_heapsize', "1024m"))
zk_server_heapsize = format("-Xmx{zk_server_heapsize_value}")
```
Instead, it should be,
```
zk_server_heapsize_value =
str(default('configurations/zookeeper-env/zk_server_heapsize', "1024"))
zk_server_heapsize_value = zk_server_heapsize_value.strip()
if len(zk_server_heapsize_value) > 0 and not
zk_server_heapsize_value[-1].isdigit():
zk_server_heapsize_value = zk_server_heapsize_value + "m"
zk_server_heapsize = format("-Xmx{zk_server_heapsize_value}")
```
