I am unable to start my datanode from Ambari. Namenode, node manager and resource manger are working fine.
The datanode on other 5 hosts are working fine.
This is the log that I am getting:

Can you please try running the following command on the DataNode (which is not starting) manually and let us know if you see any error in the "/var/log/hadoop/hdfs/hadoop-hdfs-datanode-xxxxx.log" or "/var/log/hadoop/hdfs/hadoop-hdfs-datanode-xxxxx,out" file?
# /var/lib/ambari-agent/ambari-sudo.sh su hdfs -l -s /bin/bash -c 'ulimit -c unlimited ; /usr/hdp/current/hadoop-client/sbin/hadoop-daemon.sh --config /usr/hdp/current/hadoop-client/conf start datanode'
.
- Please share those out and log files of DataNode here.
- Also please check if the PID file is pointing to the currently running DataNode PID.
Example:
# cat /var/run/hadoop/hdfs/hadoop-hdfs-datanode.pid 2212 # ps -ef | grep DataNode
.
- Also please check if the DataNode has enough Memory.
# free -m
.

Output for free -m
total used free shared buff/cache available Mem: 15870 3850 2752 648 9268 10931
Also, I guess issue is with pid value. Following is the output that i got:
[root@colo-hdop-prd01 hdfs]# cat hadoop-hdfs-datanode.pid 44745 [root@colo-hdop-prd01 hdfs]# ps -ef | grep DataNode root 45961 45856 0 02:19 pts/0 00:00:00 grep --color=auto DataNode
Please guide me if I should delete the process or what should I do

You have posted the output of the "/var/log/hadoop/hdfs/hadoop-hdfs-datanode-xxxx.out" file. We need to see the "/var/log/hadoop/hdfs/hadoop-hdfs-datanode-xxxx.log" file.
Can you please share that file it will be better if you can attach that file here, because that ".log" file may be much larger than the ".out" file.
