@Ruslan Fialkovsky You need to write a custom code which can block -skiptrash command
This is the path where you need to place the command
vi /usr/hdp/current/hadoop-client/bin/hadoop
#!/bin/bash
export HADOOP_HOME=${HADOOP_HOME:-/usr/hdp/2.6.5.0-292/hadoop}
export HADOOP_MAPRED_HOME=${HADOOP_MAPRED_HOME:-/usr/hdp/2.6.5.0-292/hadoop-mapreduce}
export HADOOP_YARN_HOME=${HADOOP_YARN_HOME:-/usr/hdp/2.6.5.0-292/hadoop-yarn}
export HADOOP_LIBEXEC_DIR=${HADOOP_HOME}/libexec
export HDP_VERSION=${HDP_VERSION:-2.6.5.0-292}
export HADOOP_OPTS="${HADOOP_OPTS} -Dhdp.version=${HDP_VERSION}"
exec /usr/hdp/2.6.5.0-292//hadoop/bin/hadoop.distro "$@"
###here you need to write code to restrict skip trash
