I have a trouble with my Accumulo installation. After hardware failure on NameNode, !METATABLE's root_tables is broken :( >From "fsck /" output: .... /accumulo/tables/!0/root_tablet/A000ornd.rf: CORRUPT block blk_-8590712379082603283 /accumulo/tables/!0/root_tablet/A000ornd.rf: MISSING 1 blocks of total size 896 B.. .... What could you recommend to recover the data? Is it possible to reconstruct !METATABLE's root_tablet based on the rest of !METATABLE files ? Or is possible to reconstruct the whole !METATABLE based on th content of the all found tablets ? Are there any ready tools to do it ? Thanks.
