I have a hadoop cluster in google cloud but in recent days I have suffered with slow queries, using beeline and hive .. beeline internally and hive externally, I have below some screens that show me errors. I would like to know how to edit the memory allocated for java. Today is -Xmx512m -Xms512 ... and wanted to switch to -Xmx1024m -Xms1024 to validate if this can bring me more performance!

Another question is .. when accessing the panel of Ambari, I see that I have a large space available .. however when accessing the system if a df -h is executed the size is not even close to what is presented in the Ambari panel. Ambari: Terminal:

Hi Guys, how are you? I have a question and I believe you can help me solve it! I have a folder with txt files that are in a directory "/ home / files" now I need to make this folder available for a hadoop query with hive, I tried to execute the command "hdfs move -p / home / files | -f / home / new" but it has not worked. I found in this manual: https://hadoop.apache.org/docs/r2.6.5/hadoop-project-dist/hadoop-hdfs/HDFSCommands.html

Hey, it worked out right .. thanks for the tip! Now another point, how do I access this directory? I tried the "hdfs dfs -cd / tmp /" command, but it did not work! I wanted to get into that directory and copy the data there with "wget" and then unzip them with a "tar -xzvf"

Hi Guys, how are you? Hope so. I have a question, see if you can help me. Everything I create through the web interface only appears in the web interface, if I create a folder in / tmp for example, via terminal, it is not available in the Ambari interface and vice-versa. Even setting groups and permissions ... I'm using IBM's Hadoop service.
