Description

If I call multiple config updates in a row, I get an exception.

I run the following in a testconfigs.sh script

/var/lib/ambari-server/resources/scripts/configs.sh -u admin -p admin set c6401.ambari.apache.org MyCluster hbase-site hbase.hstore.flush.retries.number 250
/var/lib/ambari-server/resources/scripts/configs.sh -u admin -p admin set c6401.ambari.apache.org MyCluster hbase-site hbase.hstore.flush.retries.number 121
/var/lib/ambari-server/resources/scripts/configs.sh -u admin -p admin set c6401.ambari.apache.org MyCluster hbase-site hbase.hstore.flush.retries.number 121

The second and third calls fail with the following:

USERID=admin
PASSWORD=admin
########## Performing 'set' hbase.hstore.flush.retries.number:250 on (Site:hbase-site, Tag:version1397244782000)

}########## NEW Site:hbase-site, Tag:version1397244970000

Looks like the tag version is getting re-used.

So I add in a sleep between calls.

/var/lib/ambari-server/resources/scripts/configs.sh -u admin -p admin set c6401.ambari.apache.org MyCluster hbase-site hbase.hstore.flush.retries.number 250
sleep 2
/var/lib/ambari-server/resources/scripts/configs.sh -u admin -p admin set c6401.ambari.apache.org MyCluster hbase-site hbase.hstore.flush.retries.number 121
sleep 2
/var/lib/ambari-server/resources/scripts/configs.sh -u admin -p admin set c6401.ambari.apache.org MyCluster hbase-site hbase.hstore.flush.retries.number 121

And things go thru fine, with the tag incremented properly.

USERID=admin
PASSWORD=admin

Server is functioning and available.
