Subject [jira] [Updated] (HBASE-5526) Optional file permission settings
Date Wed, 07 Mar 2012 01:51:57 GMT

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

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

    Attachment: java_HBASE-5526-v2.patch

Attaching patch for general umask application for files and directories.

Essentially, the patch takes all the file and directory creation in src/main and pipes it
through new methods in FSUtils, which automatically apply the file permissions if they are
turned on, rather than just doing the straigh fs.create() or fs.mkdirs() calls.

Unfortunately, this is a wider sweeping change than anticipated as there are a lot of places
that create files and directories. However, this helps centralize the code in the future,
if we want to more/fancier stuff to the files.

> 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.
