[SPARK-2951] [PySpark] support unpickle array.array for Python 2.6 (port to
1.0)
Pyrolite can not unpickle array.array which pickled by Python 2.6, this
patch fix it by extend Pyrolite.
There is a bug in Pyrolite when unpickle array of float/double, this patch
workaround it by reverse the endianness for float/double. This workaround
should be removed after Pyrolite have a new release to fix this issue.
I had send an PR to Pyrolite to fix it:
