Hello Team,
I
am trying to replicate MYSQL data from multiple locations(sites) to
central location. For this, we are using CaptureChangeMysql processor
at sites to send change data to central
location. We can only rely upon binary logs that taking snapshot of
tables hence the reason to use CaptureChangeMysql. We tried NIFI 3.0/4.0
at sites which will push to central instance. This is working without
any issues.
As NIFI is little heavier, we are thinking of using MINIFI 0.2 at sites ( Even tried 0.2.1 by building the source thinking
https://issues.apache.org/jira/browse/MINIFI-403
will solve but no luck) and put NIFI server at central. When we run the
MINIFI instance, we are getting following error, though we have put
recommended
libraries from NIFI instance into MINIFI Lib directory.
