On my windows machine, I am trying to use spark 2.4.6 without hadoop using - spark-2.4.6-bin-without-hadoop-scala-2.12.tgz
After setting the SPARK_HOME, HADOOP_HOME and also SPARK_DIST_CLASSPATH with information from the post linked here
when i try to start the spark-shell, I get this error -
Error: A JNI error has occurred, please check your installation and try again

The link referenced above seems and many others point to SPARK_DIST_CLASSPATH , but I already have this in my system variables as -
$HADOOP_HOME;$HADOOP_HOME\etc\hadoop*;$HADOOP_HOME\share\hadoop\common\lib*;$HADOOP_HOME\share\hadoop\common*;$HADOOP_HOME\share\hadoop\hdfs*;$HADOOP_HOME\share\hadoop\hdfs\lib*;$HADOOP_HOME\share\hadoop\hdfs*;$HADOOP_HOME\share\hadoop\yarn\lib*;$HADOOP_HOME\share\hadoop\yarn*;$HADOOP_HOME\share\hadoop\mapreduce\lib*;$HADOOP_HOME\share\hadoop\mapreduce*;$HADOOP_HOME\share\hadoop\tools\lib*;
I also have this line in the spark-env.sh of the spark -
export SPARK_DIST_CLASSPATH=$(C:\opt\spark\hadoop-2.7.3\bin\hadoop classpath)
HADOOP_HOME = C:\opt\spark\hadoop-2.7.3
SPARK_HOME = C:\opt\spark\spark-2.4.6-bin-without-hadoop-scala-2.12
When I tried the spark 2.4.5 that came with hadoop seems to work just fine. This tells me there is something wrong with the way I have my hadoop set up. What am I missing here? Thanks!
