[jira] [Commented] (HIVE-12779) Buffer underflow when inserting
data to table
[ https://issues.apache.org/jira/browse/HIVE-12779?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15204052#comment-15204052 ]
Alina Abramova commented on HIVE-12779:
---------------------------------------
I investigated this issue and see that this bug appears randomly and for me only in case concurrently running jobs in Hive which address to the same table. I ran two queries in two beelines and about one of thirty attempts finished with this exception. After investigating issues with kryo's serializer I found that this exception appears in few cases:
1) Kryo is used in multithreading env. But I see that in Hive kryo created as thread local variable and this case is excluded, I think
2) Two Input uses the same buffer. As example
Input inp1 = new Input(buff);
Input inp2 = new Input(buff);
For me suspected causes cases when Hive receives the stream to read from FileSystem, maybe two threads use the one path for reading a plan, but, in theory, it is excluded, because jobs can not have the one plan with one path.
3) When output stream was not closed after serialization, but I did not found such incidents in Hive's code after HIVE-8688.
Maybe reporter could give more information about the query for finding 100% reproducable case.
