Hi Team, I am trying to run hbase 1.2.0 in local mode using cygwin. I have followed the setup instructions in the link: https://hbase.apache.org/cygwin.html. But when I start hbase and try running the hbase shell command, I am getting the below exception. Kindly help me to resolve this issue. 2020-02-29 22:23:11,969 FATAL [CHNMCT279526L:49334.activeMasterManager] master.HMaster: Failed to become active master java.lang.NullPointerException at java.lang.ProcessBuilder.start(ProcessBuilder.java:1012) at org.apache.hadoop.util.Shell.runCommand(Shell.java:482) at org.apache.hadoop.util.Shell.run(Shell.java:455) at org.apache.hadoop.util.Shell$ShellCommandExecutor.execute(Shell.java:702) at org.apache.hadoop.util.Shell.execCommand(Shell.java:791) at org.apache.hadoop.util.Shell.execCommand(Shell.java:774) at org.apache.hadoop.fs.RawLocalFileSystem.setPermission(RawLocalFileSystem.java:646) at org.apache.hadoop.fs.RawLocalFileSystem.create(RawLocalFileSystem.java:293) at org.apache.hadoop.fs.ChecksumFileSystem.create(ChecksumFileSystem.java:451) at org.apache.hadoop.fs.ChecksumFileSystem.create(ChecksumFileSystem.java:426) at org.apache.hadoop.fs.FileSystem.create(FileSystem.java:906) at org.apache.hadoop.fs.FileSystem.create(FileSystem.java:887) at org.apache.hadoop.fs.FileSystem.create(FileSystem.java:784) at org.apache.hadoop.fs.FileSystem.create(FileSystem.java:773) at org.apache.hadoop.hbase.util.FSUtils.setVersion(FSUtils.java:727) at org.apache.hadoop.hbase.util.FSUtils.setVersion(FSUtils.java:705) at org.apache.hadoop.hbase.util.FSUtils.checkVersion(FSUtils.java:662) at org.apache.hadoop.hbase.master.MasterFileSystem.checkRootDir(MasterFileSystem.java:462) at org.apache.hadoop.hbase.master.MasterFileSystem.createInitialFileSystemLayout(MasterFileSystem.java:153) at org.apache.hadoop.hbase.master.MasterFileSystem.<init>(MasterFileSystem.java:128) at org.apache.hadoop.hbase.master.HMaster.finishActiveMasterInitialization(HMaster.java:638) at org.apache.hadoop.hbase.master.HMaster.access$500(HMaster.java:184) at org.apache.hadoop.hbase.master.HMaster$1.run(HMaster.java:1729) at java.lang.Thread.run(Thread.java:813)
