Hello,

We are using MySQL as the meta datastore. Let's say the db crashed hard and
we lost all data. What is
the process to rebuild the meta-data assuming the data on hdfs is intact.
Are there tools available to do
this ?

Your should run mysqldump and backup the database to a different
machine. This way you do not have to rebuild the meta-data. Simply
restore the database to a machine and you are done.

Edward,

Period mysql dumps is ok. But how do I sync the changes on data after the
latest
mysql dump.
