> If you set HADOOP_CLIENT_OPTS and run hadoop, you'll find that the HADOOP_CLIENT_OPTS
value gets appended twice, and leads to JVM start failures for cases like adding debug flags.
> For example,
> {noformat}
> HADOOP_CLIENT_OPTS='-agentlib:jdwp=transport=dt_socket,address=localhost:9009,server=y,suspend=y'
hadoop jar anything
> ERROR: Cannot load this JVM TI agent twice, check your java command line for duplicate
jdwp options.
> Error occurred during initialization of VM
> agent library failed to init: jdwp
> {noformat}
