core/src/main/java/org/apache/oozie/sla/SLACalculatorMemory.java <https://reviews.apache.org/r/17720/#comment76711> what happens if multipleServerRunning() gets called by server A when it's the only server, so it returns false; but then server B comes up immediately after? Will this race condition be a problem? core/src/main/java/org/apache/oozie/sla/SLACalculatorMemory.java <https://reviews.apache.org/r/17720/#comment76712> Instead of doing "instanceof", you can put "multipleServerRunning()" in JobsConcurrencyService which simply always returns "false". ZKJobsConcurrencyService would override that method (don't forget the "@Override") to actually check with ZooKeeper. - Robert Kanter On May 7, 2014, 4:46 a.m., Ryota Egashira wrote: > > ----------------------------------------------------------- > This is an automatically generated e-mail.
