Flavio Junqueira commented on BOOKKEEPER-336:
---------------------------------------------
bq. The option is client side only so it doesn't belong in bk_server.conf.
You're right, my bad.
bq. This would be nice. Has this stuff gone into ZK yet, perhaps we could reuse
some of that code. In any case, future work.
No, it implied too many changes and the guy who did it didn't push very hard
either. Here it would be a lot more focused, so less of a concern.
> bookie readEntries is taking more time if the ensemble has failed bookie(s)

> Scenario:
> 1) Start three bookies. Create ledger with ensemblesize=3, quorumsize=2
> 2) Add 100 entries to this ledger
> 3) Make first bookie down and read the entries from 0-99
> Output: Each entry is going to fetch from the failed bookie and is waiting
> for the bookie connection timeout, only after failure going to next bookie.
> This is affecting the read entry performance.
> Impact: Namenode switching time will be affected by adding this failed bookie
> readTimeOut also.
