UnsafeFixedWidthAggregationMap contains an off-by-factor-of-8 error when allocating row conversion scratch space: we take a size requirement, measured in bytes, then allocate a long array of that size. This means that we end up allocating 8x too much conversion space.
This patch fixes this by allocating a `byte[]` array instead. This doesn't impose any new limitations on the maximum sizes of UnsafeRows, since UnsafeRowConverter already used integers when calculating the size requirements for rows.

As described in SPARK-8079, when writing a DataFrame to a `HadoopFsRelation`, if `HadoopFsRelation.prepareForWriteJob` throws exception, an unexpected NPE will be thrown during job abortion. (This issue doesn't bring much damage since the job is failing anyway.)
This PR makes the job/task abortion logic in `InsertIntoHadoopFsRelation` more robust to avoid such confusing exceptions.

The `HiveThriftServer2Test` relies on proper logging behavior to assert whether the Thrift server daemon process is started successfully. However, some other jar files listed in the classpath may potentially contain an unexpected Log4J configuration file which overrides the logging behavior.
This PR writes a temporary `log4j.properties` and prepend it to driver classpath before starting the testing Thrift server process to ensure proper logging behavior.

The current code references the schema of the DataFrame to be written before checking save mode. This triggers expensive metadata discovery prematurely. For save mode other than `Append`, this metadata discovery is useless since we either ignore the result (for `Ignore` and `ErrorIfExists`) or delete existing files (for `Overwrite`) later.
This PR fixes this issue by deferring metadata discovery after save mode checking.
