Description

There are some shaded Guava dependencies coming from the Hadoop project's shaded Guava version.
It would be nice to get rid of them, as most of them are just convenience, or easy to get rid of.

The following classes are used:

• org.apache.hadoop.thirdparty.com.google.common.base.Charsets - can be replaced by java.nio.charset.StandardCharsets.UTF-8
• org.apache.hadoop.thirdparty.com.google.common.base.Preconditions. we have shaded in ratis thirdparty, we can switch to that (org.apache.ratis.thirdparty.com.google.common.base.Preconditions)
• org.apache.hadoop.thirdparty.com.google.common.collect.Lists.newXXX and Maps.newXXX can be replaced by simple constructor call
• org.apache.hadoop.thirdparty.com.google.common.annotations.VisibleForTesting - we can switch to shaded in ratis thirdparty (org.apache.ratis.thirdparty.com.google.common.annotations.VisibleForTesting)
