It’s a conflict of hadoop with Windows filesystem. SPARK-8333 causes an exception while deleting a Spark temp directory on Windows, so deploying it is not recommended. Set the environment variable HADOOP_HOME to the parent directory of bin/winutils.exe set HADOOP_HOME=%SPARK_HOME%\hadoop Since it is specifically used for Spark, I would put it under the Spark directory, for example, %SPARK_HOME%\hadoop\bin\winutils.exe.
#Download spark 2.2.0 bin hadoop2.7 download#
To fix it, download winutils.exe from Hortonworks or Github. Java.io.IOException: Could not locate executable null\bin\winutils.exe in the Hadoop binaries. ERROR Shell: Failed to locate the winutils binary in the hadoop binary path SPARK_HOME=d:\spark-examples\externals\spark\spark-2.4.5-bin-hadoop2.7ĭue to the bug SPARK-2356, Spark produces an error.

Spark is written in Scala, so the Scala API has advantages. Spark supports APIs in Scala, Python, Java and R. Creating a Spark application in Scala in stand-alone mode on a localhost is pretty straight forward.
