Hi, Probably this might help: 1. Download *winutils.exe* and *hadoop.dll* from https://github.com/steveloughran/winutils/tree/master/hadoop-2.7.1/bin 2. Put these 2 files in the */bin* folder of Drill 3. Set *HADOOP_HOME* (in environment variable) to the the directory which contains the Drill */bin *folder. Eg: If your folder structure is D:/folder1/folder2/apache-drill-some-version/bin, then set *HADOOP_HOME* to *D:/folder1/folder2/apache-drill-some-version*, so that HADOOP_HOME/bin contains winutils.exe and hadoop.dll
Please give this a try. It should solve your problem. After following the above mentioned steps, try starting Drill again. If this method works, HADOOP_HOME *won't* come out as "HADOOP_HOME not detected... ". Instead, you will get HADOOP_HOME as the path you set in the environment variable and Drill would start running fine.
