Vinay commented on BOOKKEEPER-346:
----------------------------------

Thanks Ivan,

You mean to say, After scanning all directories for *.idx files, one more time 
scan for *.idx.rloc files.

1) If one x.idx.rloc file found and corresponding x.idx not found earlier, then 
rename x.idx.rloc to x.idx and add x to activeLedgers list.
2) if x.idc.rloc file found and also x.idx was also found during first scan, 
then just delete x.idx.rloc and proceed.

Am I right?

All these things if I do in 
{{org.apache.bookkeeper.bookie.LedgerCacheImpl.getActiveLedgers()}} then no 
need of {{start()}} method. Also I can remove similar code in 
{{findIndexFile()}}
