Weiqing Yang created SPARK-18521:
------------------------------------
Summary: Add `NoRedundantStringInterpolator` Scala rule
Key: SPARK-18521
URL: https://issues.apache.org/jira/browse/SPARK-18521
Project: Spark
Issue Type: Improvement
Reporter: Weiqing Yang
Currently the s string interpolator is used in many cases in which there is no
embed variable reference in the processed string literals.
For example:
core/src/main/scala/org/apache/spark/deploy/Client.scala
{code}
logError(s"Error processing messages, exiting.")
{code}
examples/src/main/scala/org/apache/spark/examples/graphx/SynthBenchmark.scala
{code}
println(s"Creating graph...")
{code}
examples/src/main/scala/org/apache/spark/examples/mllib/LDAExample.scala
{code}
println(s"Corpus summary:")
{code}
sql/hive/src/test/scala/org/apache/spark/sql/hive/execution/SQLViewSuite.scala
{code}
test(s"correctly handle CREATE OR REPLACE TEMPORARY VIEW") {
{code}
We can add a new scala style rule 'NoRedundantStringInterpolator' to prevent
unnecessary string interpolators.
