Subject [jira] [Commented] (ACCUMULO-4043) start-up needs to scale with the number of servers
Date Thu, 16 Feb 2017 21:39:42 GMT


Christopher Tubbs commented on ACCUMULO-4043:

A start-up delay parameter, similar to the gc startup delay, could help the user decide what
the appropriate value should be for their situation.

> When starting a very large production cluster, the master gets running fast enough that
it loads the metadata table before all the tservers are registered and running. The result
is a very long balancing period after all servers started. The wait period for the tablet
server stabilization needs to scale somewhat with the number of tablet servers.
