Comment: add hive configuration directory note

...

If you are unsure which version of Avro SerDe is used, pass both serdePropKey and tablePropKey arguments with their respective values for the keys to updateLocation.

Info
titleHive Configuration Directory

Note that this command is a command for hive administrators and it needs direct access to the metastore RDBMS. In some environments, the RDBMS login information (specially password or the password key) is only stored on the metastore server host or in a metastore server specific config directory (with more restrictive file system permissions). In such cases, make sure you run on the metastore server machine, as the hive user, and also set the HIVE_CONF_DIR environment variable appropriately (for example- export HIVE_CONF_DIR=<path to metastore server config dir>).

 

Usage Example

The following metatool command uses the updateLocation, tablePropKey, and serdePropKey options to update the NameNode location to hdfs://localhost:9000 from hdfs://namenode2:8020.
