I am pretty sure that this change cannot be back ported to 1.10 as is - there must be something else going on that makes the watcher required for this version. When I make this change in 1.10, the master does not seem to load the metadata table - it gets stuck looping with: ``` (Using uno) from master log: 2020-11-25 19:26:18,420 [state.ZooTabletStateStore] DEBUG: Returning root tablet state: +r<<@(null,localhost:9997[10000f6700f0003],localhost:9997[10000f6700f0003]) 2020-11-25 19:26:18,420 [master.Master] DEBUG: Root Table location State: +r<<@(null,localhost:9997[10000f6700f0003],localhost:9997[10000f6700f0003]) 2020-11-25 19:26:18,421 [master.Master] DEBUG: [Root Table]: scan time 0.00 seconds 2020-11-25 19:26:18,421 [master.Master] DEBUG: [Root Table] sleeping for 60.00 seconds 2020-11-25 19:26:28,013 [master.Master] DEBUG: Finished gathering information from 1 of 1 servers in 0.00 seconds 2020-11-25 19:26:28,014 [master.Master] DEBUG: not balancing just yet, as collection of live tservers is in flux tserver log: it loads the root table and then not much else happens: 2020-11-25 19:21:17,540 [state.ZooTabletStateStore] DEBUG: Returning root tablet state: +r<<@(localhost:9997[10000f6700f0003],null,null) 2020-11-25 19:21:17,542 [state.ZooStore] DEBUG: Wrote localhost:9997|10000f6700f0003 to /accumulo/ca6508fd-a202-499d-a281-4e9e09aaf890/root_tablet/location 2020-11-25 19:21:17,544 [state.ZooStore] DEBUG: Wrote localhost:9997|10000f6700f0003 to /accumulo/ca6508fd-a202-499d-a281-4e9e09aaf890/root_tablet/lastlocation 2020-11-25 19:21:17,544 [state.ZooStore] DEBUG: Removing /root_tablet/future_location 2020-11-25 19:21:17,552 [state.ZooTabletStateStore] DEBUG: Put down root tablet location 2020-11-25 19:21:17,553 [tserver.TabletServer] INFO : Root tablet loaded: +r<< 2020-11-25 19:21:17,773 [tserver.TabletServer] DEBUG: ScanSess tid 127.0.0.1:57460 +r 1 entries in 0.05 secs, nbTimes = [45 45 45.00 1] 2020-11-25 19:21:17,893 [tserver.TabletServer] DEBUG: ScanSess tid 127.0.0.1:57460 +r 1 entries in 0.00 secs, nbTimes = [2 2 2.00 1] 2020-11-25 19:21:18,103 [tserver.TabletServer] DEBUG: ScanSess tid 127.0.0.1:57460 +r 1 entries in 0.00 secs, nbTimes = [1 1 1.00 1] 2020-11-25 19:21:18,504 [tserver.TabletServer] DEBUG: ScanSess tid 127.0.0.1:57460 +r 1 entries in 0.00 secs, nbTimes = [1 1 1.00 1] 2020-11-25 19:21:18,935 [server.GarbageCollectionLogger] DEBUG: gc ParNew=0.00(+0.00) secs ConcurrentMarkSweep=0.08(+0.00) secs freemem=675,633,096(-63,807,312) totalmem=778,502,144 ``` ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
