-------------------------------------------
I captured network packets by using tcpdump when the issue was reproduced. The
output is as follows:

According to the above, it seems like the message format was not correct.
Also, one more thing I noticed is that it looks like the exception in the
description indicates the client used JSON serialization:
{code}
at
org.apache.calcite.avatica.remote.JsonService.apply(JsonService.java:227)
{code}
I finally found there is Avatica jar conflict between phoenix-thin-client jar
and spark-assembly jar.
It seems like both phoenix-thin-client jar and spark-assembly jar depend on
calcite-avatica jar, but the version is different.
(In HDP-2.6.3, phoenix-thin-client jar depends on calcite-avatica-1.8.0.2.6.1.0
and spark-assembly jar depends on calcite-avatica-1.2.0-incubating.)
When I ran spark-shell with -verbose:class, the following was shown:
{code}
...
[Loaded org.apache.calcite.avatica.UnregisteredDriver from
file:/usr/hdp/2.6.3.0-235/spark/lib/spark-assembly-1.6.3.2.6.3.0-235-hadoop2.7.3.2.6.3.0-235.jar]
[Loaded org.apache.calcite.avatica.remote.Driver from
file:/usr/hdp/2.6.3.0-235/spark/lib/spark-assembly-1.6.3.2.6.3.0-235-hadoop2.7.3.2.6.3.0-235.jar]
[Loaded org.apache.calcite.avatica.Handler from
file:/usr/hdp/2.6.3.0-235/spark/lib/spark-assembly-1.6.3.2.6.3.0-235-hadoop2.7.3.2.6.3.0-235.jar]
...
{code}
This means the classes in calcite-avatica from spark-assembly jar
(1.2.0-incubating) were used.
Since calcite-avatica-1.2.0-incubating doesn't support PROTOBUF serialization
and it supports only JSON serialization, the error occurs in this case.
Therefore, we need to hide the calcite-avatica dependency in
phoenix-thin-client jar from spark-assembly jar.
