since i see you logs says that you are  downlading the parcels from /opt/cloudera/parcels/CDH-5.11.1-1.cdh5.11.1.p0.4/lib/impala/../..

it says ( in your log file ) go to

 /var/log/impalad/impalad.ERROR

it may direct to mini-dump logs (/var/log/impala-minidumps/impalad / )

if you open the file and if you come across the JRE runtime error plus if it complains about the core dump .

Then it is the bug that is related to Linux kernel , impala's JRE error .

the fix is to increase the Stack thread  . do the below steps

the error should look like this

A fatal error has been detected by the Java Runtime Environment:
#
#  SIGBUS (0x7) at pc=0x00007fa6b9f80c18, pid=3819, tid=0x00007fa6cfdb4900
#
# JRE version:  (8.0_131-b11) (build )
# Java VM: Java HotSpot(TM) 64-Bit Server VM (25.131-b11 mixed mode linux-amd64 compressed oops)
# Problematic frame:
# j  java.lang.Object.<clinit>()V+0
#
# Failed to write core dump. Core dumps have been disabled. To enable core dumping, try "ulimit -c unlimited" before starting Java again

The fix is

In  Cloduera manager UI -> Cluster -> Go to Impala - Configuration tab .

Search 

Step 1 :

Impala Daemon properties:

Impala Daemon Environment Advanced Configuration Snippet (Safety Valve)

apply the  JAVA_TOOL_OPTIONS=-Xss2m

Steo 2 :

Apply the same for Impala Catalog -

"Impala Catalog Server Environment Advanced Configuration Snippet (Safety Valve)"

before you restart the catalog daemon.

JAVA_TOOL_OPTIONS=-Xss2m

Reason - The crash was caused by a change to the linux kernel that modified the memory layout around JAVAthread stacks.
