Cannot write historyserver pid /tmp/hadoop-HX-historyserver.pid.

As an AI language model, I do not have enough context to provide a specific solution. However, this error message indicates that the historyserver process is unable to write its process ID to the specified file location (/tmp/hadoop-HX-historyserver.pid). This could be due to insufficient permissions, a full disk, or other system issues.

To troubleshoot the issue, you could try the following steps:

1. Check that the specified file directory (/tmp) exists and has sufficient permissions for the user running the historyserver process.

2. Check that the disk or partition where /tmp is located has sufficient free space.

3. Check that there are no other processes running that might be interfering with the historyserver process, such as another instance of the historyserver or a different application that is using the same file resources.

4. Check the log files for the historyserver process to see if there are any other error messages or clues about the root cause of the issue.

If none of these steps resolve the issue, you may need to seek further assistance from your system administrator or the Hadoop community.
