Greetings, on a testing platform (running HBase-0.90.3 on top of Hadoop-0.20-append), we did the following : - create a dummy table - put a single row - get this row from the shell - wait a few minutes - kill -9 the datanodes
Because regionservers could not connect to datanodes, they shutdown. On restart, the row has vanished. But if we do the same and "flush 'dummy'" from the Shell before killing the datanodes, the row is still there. Is it related to WAL ? MemStores ? What happened ? What are the recommended settings so rows are auto-flushed or at least flushed more frequently ? Regards
