Field Detail

killIfHasParent

protected volatile boolean killIfHasParent

killIfSuspended

protected volatile boolean killIfSuspended

killBeforeStoreUpdate

protected volatile boolean killBeforeStoreUpdate

Kill the PE BEFORE we store state to the WAL. Good for figuring out if a Procedure is persisting all the state it needs to recover after a crash.

toggleKillBeforeStoreUpdate

protected volatile boolean toggleKillBeforeStoreUpdate

killAfterStoreUpdate

protected volatile boolean killAfterStoreUpdate

Set when we want to fail AFTER state has been stored into the WAL. Rarely used. HBASE-20978 is about a case where memory-state was being set after store to WAL where a crash could cause us to get stuck. This flag allows killing at what was a vulnerable time.

toggleKillAfterStoreUpdate

protected volatile boolean toggleKillAfterStoreUpdate
