[jira] [Updated] (HADOOP-14202) fix jsvc/secure user var
inconsistencies
[ https://issues.apache.org/jira/browse/HADOOP-14202?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Allen Wittenauer updated HADOOP-14202:
--------------------------------------
Attachment: HADOOP-14202.03.patch
-03:
* remove some more shellcheck overrides that are no longer needed
* updated documentation to address feedback
* fix a bug with JSVC_HOME where the default wasn't actually being set
* flip the return state for hadoop_detect_priv_subcmd
* add a test for hadoop_detect_priv_subcmd
* add a check for SECURE_USER in hadoop_uservar_su to default to a working state if the current process is privileged but _USER is undefined
* check the error message for hadoop_uservar_su because if we are trying to stop a daemon "launch" makes zero sense.
* rework hadoop_generic_java_subcmd_handler a bit to better handle 3rd party stuff and make the comments more sane
* clean up hadoop-env.sh to reflect reality

> Post-HADOOP-13341 and (more importantly) HADOOP-13673, there has been a major effort on making the configuration environment variables consistent among all the projects. The vast majority of vars now look like (command)_(subcommand)_(etc). Two hold outs are HADOOP_SECURE_DN_USER and HADOOP_PRIVILEGED_NFS_USER.
> Additionally, there is
> * no generic handling
> * no documentation for anyone
> * no safety checks to make sure things are defined
> In order to fix all of this, we should:
> * deprecate the previous vars using the deprecation function, updating the HDFS documentation that references them
> * add generic (command)_(subcommand)_SECURE_USER support
> * add some verification for the previously mentioned var
> * add some docs to UnixShellGuide.md
