Subject [jira] [Updated] (HBASE-5526) Configurable file and directory based umask
Date Wed, 07 Mar 2012 06:53:58 GMT

     [ https://issues.apache.org/jira/browse/HBASE-5526?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Jesse Yates updated HBASE-5526:
-------------------------------

    Description: 
Currently many all the files created by the HBase user are just written using the default
file permissions granted by hdfs. However, to ensure only the correct user/group views the
files and directories, we need to be able to apply a configurable umask to either directories
or files. 

This ticket covers setting permissions for files written to dfs, as opposed to things like
pid and log files.

The impetus for this was to allow the web-user to view the directory structure of hbase, but
not to actually see any of the actual data hbase is storing.

  was:
Currently many all the files created by the HBase user are just written using the default
file permissions granted by hdfs. However, it is often times adventageous to only allow a
subset of the world to view the actual data written by hbase when scanning the raw hdfs files.


This ticket covers setting permissions for files written to hdfs that are storing actual user
data, as opposed to _all_ files written to hdfs as many of them contain non-identifiable metadata.

        Summary: Configurable file and directory based umask  (was: Optional file permission
settings)
