For struct type, if parquet's global schema has less fields than a file's schema, data reading will fail
[Spark SQL] All result records will be popluated into ONE line during the script transform due to missing the correct line/filed delimiter
Flaky test: o.a.s.streaming.InputStreamSuite - socket input stream
Struct fields read from parquet are mis-aligned
Flaky test: o.a.s.metrics.InputOutputMetricsSuite - input metrics with cache and coalesce
The PySpark 1.5 closure serializer can't serialize a namedtuple instance.
Multiple Python UDFs together with aggregation or sort merge join may cause OOM (failed to acquire memory)
