Chia-Ping Tsai commented on HBASE-19046:
----------------------------------------
{code}
if (this.getCoprocessorHost() != null) {
this.getCoprocessorHost().postCompactSelection(
this, ImmutableList.copyOf(compaction.getRequest().getFiles()),
tracker,
compaction.getRequest(), user);
}
{code}
We can pass {{Collections.unmodifiableList()}} now. It doesn't makes a copy of
all elements from input list.

> Dont think there is any specific need for passing this PB type. We can just
> pass an unmodifiableList list object. Javadoc can say this is an
> unmodifiableList . Thats it . No need that the type itself to be
> Immutable...
