----------------------------------

             Summary: Ignore comment syntax in dfs command
                 Key: SPARK-39380
                 URL: https://issues.apache.org/jira/browse/SPARK-39380
             Project: Spark
          Issue Type: Bug
          Components: SQL
    Affects Versions: 3.2.1
            Reporter: Chen Zhang


In version 3.2, Spark SQL ignores semicolons in comment syntax when splitting input lines. 

This behavior throws an unexpected dfs command error:

mkdir testDfsCommand
echo 'abc' > testDfsCommand/a---.txt
​
./spark-2.4.8-bin-hadoop2.7/bin/spark-sql -e 'dfs -cat testDfsCommand/a---.txt;'
# abc
./spark-2.4.8-bin-hadoop2.7/bin/spark-sql -e 'dfs -cat testDfsCommand/*;'
# abc
​
./spark-3.2.1-bin-hadoop2.7/bin/spark-sql -e 'dfs -cat testDfsCommand/a---.txt;'
# cat: `testDfsCommand/a---.txt;': No such file or directory
# Command -cat testDfsCommand/a---.txt; failed with exit code = 1
./spark-3.2.1-bin-hadoop2.7/bin/spark-sql -e 'dfs -cat testDfsCommand/*;'
# cat: `testDfsCommand/*;': No such file or directory
# Command -cat testDfsCommand/*; failed with exit code = 1
