Ted Yu commented on HBASE-14450:
--------------------------------

After more debugging, walRoller.requestRollAll() should be called for the 
multiwal case.

Currently LogRoller doesn't expose any API for the caller to know when the log 
roll for all WALs has completed.

I temporarily add a pause following requestRollAll() so that the test passes 
but this is just workaround.
