Find whether file exists or not in HDFS using shell script

You can try -test option to achieve the same.

hdfs dfs -test -[defszrw] HDFS_PATH

• -d: if the path is a directory, return 0.
• -e: if the path exists, return 0.

Since 2.7.0

• -f: if the path is a file, return 0.
• -s: if the path is not empty, return 0.
• -r: if the path exists and read permission is granted, return 0.

since 2.8.0

• -w: if the path exists and write permission is granted, return 0.
• -z: if the file is zero-length, return 0.

Example:

if hdfs dfs -test -e $HDFS_PATH; then
    echo "[$HDFS_PATH] exists on HDFS"
    hdfs dfs -ls $HDFS_PATH
fi
