Toshihiro Suzuki commented on PHOENIX-4466:
-------------------------------------------
[~elserj] I'm sorry for the confusion.
Let me explain it chronologically.
1. We were facing the protocol mismatch error as explained in the description.
2. To avoid the the protocol mismatch error, we tried to run spark-shell with
spark.{driver,executor}.userClassPathFirst, but it failed with the following
error you mentioned:
{code}
# spark-shell --jars /usr/hdp/current/phoenix-client/phoenix-thin-client.jar
--conf spark.driver.userClassPathFirst=true --conf
spark.executor.userClassPathFirst=true
...
scala> val query =
sqlContext.read.format("jdbc").option("driver","org.apache.phoenix.queryserver.client.Driver").option("url","jdbc:phoenix:thin:url=http://<phoenix
query server hostname>:8765;serialization=PROTOBUF").option("dbtable","<table
name>").load
...
Exception in thread "main" java.lang.RuntimeException:
java.lang.RuntimeException: class
org.apache.hadoop.security.JniBasedUnixGroupsMappingWithFallback not
org.apache.hadoop.security.GroupMappingServiceProvider
...
{code}
JniBasedUnixGroupsMappingWithFallback and GroupMappingServiceProvider are in
both spark-assembly jar and phoenix-thin-client jar and the version is same in
HDP-2.6.3, but the above error occurred. So we thought there was a problem
around classloader when specifying spark.{driver,executor}.userClassPathFirst.
3. We built a dev jar (phoenix-4.7.0.2.6.1.0-SNAPSHOT-thin-client.jar)
relocating hadoop-common and tried with it, and the classloader error
disappeared but the first error re-occurred for some reason.
{code}
# spark-shell --jars phoenix-4.7.0.2.6.1.0-SNAPSHOT-thin-client.jar --conf
spark.driver.userClassPathFirst=true --conf
spark.executor.userClassPathFirst=true
...
scala> val query =
sqlContext.read.format("jdbc").option("driver","org.apache.phoenix.queryserver.client.Driver").option("url","jdbc:phoenix:thin:url=http://<phoenix
query server hostname>:8765;serialization=PROTOBUF").option("dbtable","<table
name>").load
...

{code}
So I thought the userClassPathFirst was either insufficient or broken and we
were not able to use it. And we needed to relocate Avatica to use Avatica
classes from phoenix-thin-client jar. Also, I thought if we don't use
userClassPathFirst, the hadoop-common relocation wasn't needed.
4. Finally, I built a new dev jar with the following relocation config (only
Avatica is relocated) and all the errors disappeared.
{code}
<relocation>
<pattern>org.apache.calcite.avatica</pattern>
<shadedPattern>${shaded.package}.org.apache.calcite.avatica</shadedPattern>
<!-- The protobuf messages can't be relocated due to a limitation
in the Avatica protocol. -->
<excludes>
<exclude>org.apache.calcite.avatica.proto.*</exclude>
</excludes>
</relocation>
{code}
Note that we need to exclude proto package due to a limitation in the Avatica
protocol.
By the way, [~pbhardwaj] tested the dev jar (relocating only Avatica) in secure
cluster and it was successful with a little bit URL change (adding
authentication=SPNEGO, principal name and keytab path).
