[Issue]Ambari HDFS parameters configuration checking errors in HAWQ
2.0.0.0 with HDP 2.4.2.0-258
Hi,
while "run service check" for HAWQ within Ambari, you may get such errors:
1.
20161207:14:48:29:182323
gpcheck:hlamaster02:gpadmin-[ERROR]:-host(hlamaster01): HDFS configuration:
expected 'dfs.namenode.accesstime.precision' for '-1', actual value is '0'
*"0" is the recommend value in the HAWQ documents. *
*May we need updating the corresponding value in "gpcheck.cnf"?*
2.
20161207:14:48:29:182323
gpcheck:hlamaster02:gpadmin-[ERROR]:-host(hlamaster01): HDFS configuration
missing: 'dfs.client.enable.read.from.local' needs to be set to 'true'
*There are a similar parameters in HDFS*
*"dfs.client.read.shortcircuit"*
*Is 'dfs.client.enable.read.from.local' actually needed?*
*If yes, is that because "libhdfs3" is used instead of the standard apache
hdfs lib?*
*If yes again, adding a <description> segment for this both in documents
and "gpcheck.cnf" may be a good idea.*
3.
20161207:14:48:29:182323
gpcheck:hlamaster02:gpadmin-[ERROR]:-host(hlamaster01): HDFS configuration
missing: 'ipc.server.handler.queue.size' needs to be set to '3300'
*I am not able to find any information about
'ipc.server.handler.queue.size' in the HAWQ 2.0.0 documents.*
*Is this a deprecated parameter inherited from Pivotal HD 2.1.0?*

Re: [Issue]Ambari HDFS parameters configuration checking errors in

Hi,
4.In http://hdb.docs.pivotal.io/200/hdb/install/install-cli.html & "hawq
check"
net.ipv4.ip_local_port_range = 1281 65535
While in Ambari,
sysctl.net.ipv4.ip_local_port_range = 1025 65535
5. I did not find a proper interface for submitting issues to Apache HAWQ
JIRA. Any hint?
Best regards,
*Parker Han*
