[jira] [Commented] (PIG-5372) SAMPLE/RANDOM(udf) before skewed join failing with NPE

Wow that's back in 2010 :). I think SkewedPartitioner.setConf is passing conf
to MapRedUtil.loadPartitionFileFromLocalCache via PigMapReduce.sJobConf. This
is no longer necessary as MapRedUtil.loadPartitionFileFromLocalCache takes
mapConf parameter (in a later patch). We can change
MapRedUtil.loadPartitionFileFromLocalCache to retrieve
fs.file.impl/fs.hdfs.impl from mapConf. Then we don't need overwrite
PigMapReduce.sJobConf in SkewedPartitioner.setConf.

[jira] [Commented] (PIG-5373) InterRecordReader might skip records if certain sync markers are used

Nandor Kollar commented on PIG-5373:
I have one observation to the patch: to be future-proof, instead
CircularFifoBuffer from commons-collection I think we should use
CircularFifoQueue from commons-collections4. On one hand CircularFifoBuffer was
removed from the latest commons collections code, on the other hand
CircularFifoQueue is generic, so we can eliminated iterating through Object
items and casting to integer. Be aware of one thing: the semantic of isFull has
changed, CircularFifoQueue is never full. The isFull call should be replaced to
{{queue.size() == queue.maxSize()}}.

> Due to bug in InterRecordReader#skipUntilMarkerOrSplitEndOrEOF(), it can
> happen that sync markers are not identified while reading the interim binary
> file used to hold data between jobs.
> In such files sync markers are placed upon writing, which later help during
> reading the data. These are random generated and it seems like that in some
> rare combinations of markers and data preceding it, they cannot be not found.
> This can result in reading through all the bytes (looking for the marker) and
> reaching split end or EOF, and extracting no records at all.
> This symptom is also observable from JobHistory stats, where if a job is
> affected by this issue, will have tasks that have HDFS_BYTES_READ or
> FILE_BYTES_READ about equal to the number bytes of the split, but at the same
> time having MAP_INPUT_RECORDS=0
> One such (test) example is this:
> {code:java}
> marker: [-128, -128, 4] , data: [127, -1, 2, -128, -128, -128, 4, 1, 2,
> 3]{code}
> Due to a bug, such markers whose prefix overlap with the last data chunk are
> not seen by the reader.
