Hi all,

I'm using Hive with the s3native FS. Today, I noticed that hive locks up after 4 queries that directly access S3 (select * from mytable limit 10). With debug logging on, I get the following output:

Does anyone know if I can do anything to prevent this? It looks like connections are not returned correctly to the pool..

    Could you please tell us which Hadoop and Hive version are you using?
    Looks like you might be using an older version of Hadoop (more specifically one which ships with old version of jets3t).

    Thanks

    Hi!

    I'm using Hive 0.7.0 and Hadoop 0.20, both from Cloudera's cdh3u0. Jets3t is used from jets3t-0.6.1.jar. I've just found a post (https://forums.aws.amazon.com/thread.jspa?threadID=19076&tstart=0) that describes this issue and I'm trying to figure out if this bug is in this version.

    Hi Wouter

    You may want to upgrade to jets3t 0.7.1 or higher which will likely solve your problem. The release notes of jets3t 0.7.1 do say :
    REST implementation was mistakenly limited to 20 simultaneous connections.

    Alternatively, you can avoid some of these types of problems by using Amazon Elastic MapReduce.

    Thanks
