graphx it's now surpport semantic graphs and have data lake?
BlockGenerator may lost data in the last block
Memory leak in SQL parsers
[Spark SQL] All result records will be popluated into ONE line during the script transform due to missing the correct line/filed delimiter
Failed batches are never reported through the StreamingListener interface
Flaky test: o.a.s.metrics.InputOutputMetricsSuite - input metrics with cache and coalesce

For struct type, if parquet's global schema has less fields than a file's schema, data reading will fail
Flaky test: o.a.s.streaming.InputStreamSuite - socket input stream
