Jonathan Eagles commented on TEZ-3165:
--------------------------------------
[~sseth], it was found that both pig's
[HBaseStorage|https://github.com/apache/pig/blob/branch-0.14/src/org/apache/pig/backend/hadoop/hbase/HBaseStorage.java]
and elephant-bird's
[SequenceFileStorage|https://github.com/twitter/elephant-bird/blob/master/pig/src/main/java/com/twitter/elephantbird/pig/util/SequenceFileConfig.java]
use OptionBuilder which is not thread-safe ([Thread-safety
notice|https://commons.apache.org/proper/commons-cli/javadocs/api-release/org/apache/commons/cli/OptionBuilder.html])
{noformat}
myinput = load 'hbase://mydb:mytable' using
org.apache.pig.backend.hadoop.hbase.HBaseStorage('d:m','-loadKey true $OPTIONS')
...
store output into 'myoutput' using
com.twitter.elephantbird.pig.store.SequenceFileStorage('-c
com.twitter.elephantbird.pig.util.TextConverter','-c
com.twitter.elephantbird.pig.util.TextConverter');
{noformat}
In this case we need to be able to completely serialize the initializations of
pig's processor, inputs, and outputs to avoid this condition. The fixes to pig
and elephant bird are in process, but this will allow compatibility mode for
the mode widely used versions as well as user defined functions which
potentially have the same issue.
> Parallel initialization of inputs, outputs, and processor can cause
