-------------------------------------
Summary: Block `reset` command in SparkShell
Key: SPARK-14102
URL: https://issues.apache.org/jira/browse/SPARK-14102
Project: Spark
Issue Type: Improvement
Components: Spark Shell
Reporter: Dongjoon Hyun
Priority: Minor
Spark Shell provides an easy way to use Spark in Scala environment. This issue
proposes to block `reset` command provided by default.
{code:title=bin/spark-shell|borderStyle=solid}
scala> sc
res0: org.apache.spark.SparkContext = org.apache.spark.SparkContext@718fad24
scala> :reset
scala> sc
<console>:11: error: not found: value sc
sc
^
{code}
If we blocks `reset`, Spark Shell works like the followings.
{code:title=bin/spark-shell|borderStyle=solid}
scala> :reset
reset: no such command. Type :help for help.
scala> :re
re is ambiguous: did you mean :replay or :require?
{code}
