Adriano updated IMPALA-8852:
----------------------------
Description:
On coordinator only nodes ([typically the edge
nodes|https://www.cloudera.com/documentation/enterprise/5-15-x/topics/impala_dedicated_coordinator.html#concept_omm_gf1_n2b]):
{code:java}
--is_coordinator=true
--is_executor=false
{code}
the *dfs.domain.socket.path* (can be nonexistent on the local FS as the
Datanode role eventually is not installed on the edge node).
The non existing path prevent the ImpalaD to start with the message:
{code:java}
I0809 04:15:53.899714 25364 status.cc:124] Invalid short-circuit reads
configuration:
- Impala cannot read or execute the parent directory of dfs.domain.socket.path

{code}
despite a coordinator-only ImpalaD does not do short circuit reads.
