Customer reflects that is unclear to know how to configure the tiflash.toml by following this page

[lokiloveu1]

File: /release-1.3/en/deploy-tiflash.md

Customer didn't notice that it's necessary to add 'tmp_path' parameter here in the tiflash.toml file by following the steps.

'''
tmp_path = "/tidb-data/tiflash-9000/tmp"
'''

Could you plz make it more obvious in the steps?

Thanks!

@DanielZhangQD PTAL. How can we improve this doc?

@lokiloveu1 This is a bug introduced in v1.3.0-beta.1, please use the latest version, e.g. v1.3.2, and no need to configure this parameter explicitly.
Refer to https://docs.pingcap.com/tidb-in-kubernetes/stable/whats-new-in-v1.3#compatibility-changes:

Due to the issue in [#4435](https://github.com/pingcap/tidb-operator/pull/4435), when using TiDB Operator v1.3.0 or v1.3.0-beta.1, you must set the tmp_path field in TiFlash's config to use TiFlash v5.4.0 or later versions. It is recommended that you upgrade TiDB Operator to v1.3.1 or later versions before you deploy TiFlash.
