-------------------------------------
Summary: Integrating Ozone with Hive produce a thread leak in HS2
server
Key: HDDS-6102
URL: https://issues.apache.org/jira/browse/HDDS-6102
Project: Apache Ozone
Issue Type: Bug
Components: OFS
Affects Versions: 1.1.0
Environment: ozone: 1.1.0
hadoop: 3.1.1
hive: 3.1.0
tez: 0.10.0 (this version is needed because of
[TEZ-4032|https://issues.apache.org/jira/browse/TEZ-4032])
both the hadoop cluster + ozone are secured using kerberos.
Reporter: Diego Jaramillo
Integration ozone with hive is producing a thread leak in HS2, in this sample,
12 open connections to hive produced 149 threads and the count kept increasing
until HS2 needed to be restarted.
SETTINGS:
HDFS integration using the following settings
- viewfs-mount-table:
fs.viewfs.mounttable.clusters.link./cluster1=hdfs://cluster1
fs.viewfs.mounttable.clusters.link./ozfs1=ofs://ozfs1
- core-site.xml:
fs.ofs.impl=org.apache.hadoop.fs.ozone.RootedOzoneFileSystem
fs.AbstractFileSystem.o3fs.impl=org.apache.hadoop.fs.ozone.OzFs
- hdfs-site.xml:
ozone.om.service.ids=ozfs1
ozone.om.nodes.ozfs1=om1,om2
ozone.om.address.ozfs1.om1=ozone1.domain.com:9862
ozone.om.address.ozfs1.om2=ozone2.domain.com:9862
dfs.nameservices=cluster1,ozfs1
ozone.om.kerberos.keytab.file=/etc/security/keytabs/om.service.keytab
ozone.om.kerberos.principal=om/_h...@domain.com
Hive integration using the following setting
- hive-site.xml:
tez.job.fs-servers=hdfs://cluster1,ofs://ozfs1
