Nicolas Colomer updated KNOX-1744:
----------------------------------
Description:
The executor logs (stdout/stderr) links from the Yarn UI Service all directly
points to the slaves nodes.
!image-2019-01-22-13-11-55-412.png!
Eg. the link:
{noformat}
http://emr-slave-hostname:8042/node/containerlogs/container_1547901130703_0034_01_000001/hadoop/stdout?start=-4096{noformat}
Should have been instead:
{noformat}
https://knox/gateway/cluster/yarn/nodemanager/node/containerlogs/container_1547901130703_0034_01_000001/hadoop?scheme=http&host=emr-slave-hostname&port=8042{noformat}
And finally respect pattern:
{noformat}
https://knox/gateway/emr/yarn/nodemanager/node/containerlogs/{your container
id}/hadoop?scheme=http&host={executor host}&port=8042 {noformat}
I guess adding some voodoo in the Knox yarnui's
[rewrite.xml|https://github.com/apache/knox/blob/master/gateway-service-definitions/src/main/resources/services/yarnui/2.7.0/rewrite.xml]
file might be enough to fix this.
