[jira] [Created] (HIVE-26255) Drop custom code for String deduplication inside URI class

Sylwester Lachiewicz created HIVE-26255:
-------------------------------------------

             Summary: Drop custom code for String deduplication inside URI class
                 Key: HIVE-26255
                 URL: https://issues.apache.org/jira/browse/HIVE-26255
             Project: Hive
          Issue Type: Improvement
            Reporter: Sylwester Lachiewicz


We have class [https://github.com/apache/hive/blob/master/common/src/java/org/apache/hadoop/hive/common/StringInternUtils.java] to do String.intern() inside the URI class via reflection.

Instead, we can recommend using newer java and enabling String deduplication
