> Disabling sanity checks on a table is ignored when restoring snapshots. If this is expected behavior at least the error message is misleading.
> h3. Steps *to Reproduce*
>  # Create a new table
> {{create 't', 'cf'}}
>  # Add a coprocessor to the newly created table
> {{alter 't', METHOD => 'table_att', 'coprocessor' => 'coprocessor.jar|com.example.MyCoprocessor|0'}}
>  # Create a snapshot
> {{snapshot 't', 'snapshot-t'}}
>  # Disable the table to prevent region servers from crashing in the next step
> {{disable 't'}}
>  # Delete the coprocessor JAR and restart HBase.
>  # Attempt to restore the snapshot leads to failing sanity check as expected
> {{restore_snapshot 'snapshot-t'}}
> {{ERROR: org.apache.hadoop.hbase.DoNotRetryIOException: coprocessor.jar Set hbase.table.sanity.checks to false at conf or table descriptor if you want to bypass sanity checks [...]}}
>  # Disable sanity checks (as described in the error message) and retry
> {{alter 't', CONFIGURATION => \{'hbase.table.sanity.checks' => 'false'}}}
> {{restore_snapshot 'snapshot-t'}}
> h3. Expected Behavior
> The snapshot is restored.
> h3. Actual Behavior
> The same error message as in step 6. is shown.
