Todd & Andrew ID'd the problem as being that the libjemalloc.so ->
(real lib) link doesn't always exist for whatever reason. I hacked our
run script to try the 3 possibilities mentioned in the ticket in this order
1) libjemalloc.so
2) libjemalloc.so.1
3) libjemalloc.so.2
Failing that, it will fall back to an empty LD_PRELOAD, so libc
would be used for the allocator.
Fixes the immediate problem. The lib_bin and server_id vars mentioned
in the ticket are untouched by this commit.
Linking will become an issue for the unified build and it is an issue
for jemalloc 5.x. Instead we will LD_PRELOAD on the forked ColumnStore
specific processes.
ColumnStore now uses standard bin/lib paths for pretty much everything.
Data path is now hard-coded to /var/lib/columnstore.
This patch also:
* Removes v1 decompression
* Removes a bunch of unneeded files
* Removes COLUMNSTORE_INSTALL_DIR / $INSTALLDIR
* Makes my.cnf.d work for all platforms (MCOL-3558)
* Changes configcpp to use recursive mutex (fixes possible config write deadlock)
* Fixes MCOL-3599 Fix regr functions, The library was installed in the wrong location
* Fixes a bunch of Ubuntu packaging issues
* Changes the binary names of several of the executables so as not to
clash with potential executables from other packages
