Hi, Our Accumulo deployment uses custom Authenticator and Authorizer and also attaches few custom filters/iterators to tables during scan time. The challenge is that we are seeing very slow response when loading the table inside a spark shell and doing a simple count. I was thinking of adding logs to all our custom components to collect metrics then I came across Accumulo Tracer which seems, somehow, targets the same concerns but requires its own custom coding and also, so far, I don't find the content of the trace table very easy to read/interpret.
Any suggestions/recommendations? Thanks,
