arvindshmicrosoft commented on issue #1568: Support multiple tservers / node in 
accumulo-service
URL: https://github.com/apache/accumulo/pull/1568#issuecomment-603590280
 
 
   @ctubbsii I have redone this PR (hence the force push). Hopefully this 
version is more aligned with the guiding principles for the 2 scripts. One 
thing I'd like advice on (in addition to any other comments) is: given that 
accumulo-cluster currently does not source accumulo-env.sh, the user must 
export NUM_TSERVERS prior to invoking accumulo-cluster. This is probably fine 
for dev/test but I was hoping to define the variable somewhere on the node 
itself. Any thoughts on sourcing accumulo-env.sh in accumulo-cluster itself?
   
   I also observed in single-node testing (with Uno) with 2 TServers is that 
the user has to set gc.port.client to a number such as 10002 to avoid having GC 
pick port 9998 - which GC cannot - since 9998 has already been used by the 
second TServer running. So the second question I have is why do these scripts 
start TServers first, ahead of master, monitor and GC?
   
   I will try joining the Slack chat on Wednesday to discuss further if needed. 
Thank you and @keith-turner for working through this with me.
