Harsh J commented on HADOOP-7930:
---------------------------------
Some comments:
- Use the CommonConfigurationKeysPublic class to constant-ize the config
strings and its defaults. See the file to get an example. Use these constants
in the code - instead of hardcoding the config string and the default this way:
{code}
+ try {
+ kerberosMinTimeBeforeRelogin = 1000L * conf.getLong(
+ "hadoop.kerberos.min.time.before.relogin", 60);
{code}
> Kerberos relogin interval in UserGroupInformation should be configurable
