Subject Re: Is the updating compaction strategy from 'sized tiered' to 'leveled' automatic or need to be done manually?
Date Mon, 05 May 2014 23:16:30 GMT
I tried to run 'nodetool compact' (or with keyspace and cfname), seemed not
woking. The command hung there and nothing happened. But I noticed that
there was about more 30000+ pending tasks when using 'nodetool
compactionsats'
