Support for doing GC on LOB data files and removing functionality from
mxlobsrvr process TRAFODION-1848
The following set of changes are being committed :
1. Moved all calls made in mxlobsrvr process into the master. Removed
interprocess sned/recieve calls and made them function calls all done within
master. Retianed the minimum infrastructure to mxlobsrvr but it's not started
anymore during sqstart.
2. Add a new LOB call to perform GC. Made this a new CLI call so we could
extend it later to be a utility that can be called offline. For now this CLI
cll will be triggered if a certain threshold is met during an
insert/update/append operation. This GC is done per lob column (i.e per lob
data file). Each lob column's GC can be done independently and do not need to
be done all at once. Dpeneds on how much space each lob column ins occupying.
3 . Removed all uses of hardcoded references ot lob location and hdfsServer
and hdfs port. ALl these are set via CQDs and are passed in to needed Tdbs.
4. A new testcase has been added to executor/TEST130 to exercise the new
code.
