Hi,I installed hadoop cluster using HDP3.0 but hbase does not work due to this error:

Looks it is caused by nonexec permission of /tmp. To make hbase not use /tmp, I added:

{ "hbase-site": { "properties": { "hbase.tmp.dir": "/u01/tmp" } } }

But this does not work and hbase still uses /tmp. Any idea? Appreciate any help.

Hi @Lian Jiang ,

Can you give some more details about the issue.

Like your operating system, Internal memory

are you trying to deploy the HDP3.0 using cloudbreak ?

Additionally, this error is at Netty, a third party app used by HDP services to deploy containers .

I found something similar here : https://github.com/netty/netty/issues/6678

Seems this is related.

Thanks Akhil S Naik

OS: oracle linux 7,

memory: 314g

deployment tool: ambari 2.7 blueprint.

Is HDP3.0 using the netty having bug 6678 fixed? 6678 seems to be just a warning. But it failed hbase in my case. Any solution? Thanks.

This problem is resolved by adding hbase.netty.nativetransport = false.

Do you foresee any issue using this fix? @Akhil S Naik

Thanks.

[UPDATE 8/15/2018]

This setting works and may be better than the above one:

{ "hbase-env": { "properties": { "hbase_java_io_tmpdir": "/u01/tmp" } } },

Hi @Lian Jiang,

Glad that your issue resolved.

changing the hbase temp directory solution is best IMHO .
