> As part of removing guava dependencies HADOOP-17115, HADOOP-17721, HADOOP-17722 and HADOOP-17720 are fixed,
> Currently the code call util function to create HashSet and TreeSet in the repo . These function calls dont have much importance as it is calling internally new HashSet<> / new TreeSet<> from java.utils
> This task is to clean up all the function calls to create sets which is redundant
> Before moving to java8 , sets were created using guava functions and API , now since this is moved away and util code in the hadoop now looks like
> 1.
> public static <E extends Comparable> TreeSet<E> newTreeSet() { return new TreeSet<E>();
> 2.
> public static <E> HashSet<E> newHashSet()
> { return new HashSet(); }
> These interfaces dont do anything much just a extra layer of function call
> please refer to the task
> https://issues.apache.org/jira/browse/HADOOP-17726
> Can anyone review if this ticket add some value in the code.
> Looking forward to some input/ thoughts . If not adding any value we can close it and not move forward with changes !
