I am trying to install five node Hadoop cluster. Following is the environmental setup. After the installation, the "datanode" service is failing to start. I can see the following log message in stderr log.
<verbosegc xmlns="http://www.ibm.com/j9/verbosegc" version="R27_Java727_SR3_20151022_1530_B273253_CMPRSS">JVMJ9VM007E Command-line option unrecognised: -Xloggc:/var/log/hadoop/hdfs/gc.log-201608121113</verbosegc>Error: Could not create the Java Virtual Machine.Error: A fatal exception has occurred. Program will exit.
Curious whether "java" is causing the issue. I am attaching the detailed log messages.
Can you please share your thoughts on this? Thanks.

Can you please double check below error:
Command-line option unrecognised: -Xloggc:/var/log/hadoop/hdfs/gc.log-201608121113
Looks like there is some special character in -Xloggc:/var/log/hadoop/hdfs/gc.log-201608121113
Please try to remove -Xloggc:/var/log/hadoop/hdfs/gc.log-201608121113 from your env files and try to start datanodes again.
Let me know how it goes.
Can you give me some idea how to fix and what steps to follow , i am also getting similar error while starting the datanode . Please help
