Hive derby/mysql installation - hadoop

Question

I have 2 queries from the below logs:
How to get rid of the first line WARN message.
Why is Hive complaining about the xml as its correctly formatted or am i missing something.

Answer 1

The issue is Hadoop "Path" doesn't support ':' in filenames.
So, replace ${system:java.io.tmpdir}/${system:user.name} by /tmp/mydir in hive-site.xml

Answer 2

I also faced the same issue.#partha is right. The issue is Hadoop "Path" doesn't support ':' in filenames.
So i modified the hive-site.xml with following properties and it worked.
<name>hive.exec.scratchdir</name>
<value>/tmp/hive-${user.name}</value>
<name>hive.exec.local.scratchdir</name>
<value>/tmp/${user.name}</value>
<name>hive.downloaded.resources.dir</name>
<value>/tmp/${user.name}_resources</value>

Regarding the first line WARN message,
the warning tells you that the hive.metastore.local key is not used. Try to remove this configuration from your hive-site.xml, if you are more concerned about removing the warning
