My hadoop crashes suddenly and not coming out from safe mode. i take back
up of my data, format it, and make my hadoop cluster to come out from safe
mode but now i have no table in hive-warehouse. How can i recover/transfer
hive data-warehouse data.

Hello,
See your mMetastore to know where your data are stored in HDFS, and you can
recover it directely esle dont' change your hive metastore and repar your
hadoop system ;)
