I was trying out the Transparent data at rest encryption and was able to
setup the KMS, zones etc. and add

Do you know why the 3 nodes are down ? With replication, the copy of data
that were hosted on those failed nodes will not be available. However, the

Hello,
I was wondering what are the main differences between LCE and DCE under '
*simple*' Hadoop security.
From my readings LCE gives:
- granularity to control execution like ban users, min uid
- use cgroups to control resources
While DCE uses ulimits.

Hi Giri,
Have you tried the COALESCE function:

example for a date column type:
hive select COALESCE(dt, cast('2014-02-23' as date)) from simpletest;
In any case, maybe good to post the
Hello,
The 3 main settings in hdfs-site.xml are:
- * dfs.name.dir*: directory where namenode stores its metadata,
default value ${hadoop.tmp.dir}/dfs/name.
- *dfs.data.dir:* directory where HDFS data blocks are stored,
default value ${hadoop.tmp.dir}/dfs/data.

Subject: DataNode logs have exceptions
Forgot to ask...
- Is this a new behavior in Ambari 2.1, I don't remember seeing it in
Ambari 1.7
- Does a JIRA already exist for any of the components to track this.
Thanks,
