Configuring HBase Parameters

Updated at: Nov 06, 2019 GMT+08:00

If the default parameter settings of the MRS service cannot meet your requirements, you can modify the parameter settings as required.

  1. Go to the cluster details page and choose Components.

    For MRS 2.0.1 or earlier, log in to MRS Manager. For details, see Accessing MRS Manager. Then, choose Services.

  2. Choose HBase > Service Configuration and set Type to All. On the displayed HBase configuration page, modify parameter settings.

    Table 1 HBase Parameters

    Parameter

    Description

    Value

    hbase.regionserver.hfile.durable.sync

    Whether to enable the HFile durability to make data persistence on disks. If this parameter is set to true, HBase performance is affected because each HFile is synchronized to disks by hadoop fsync when being written to HBase.

    This parameter exists only in versions earlier than MRS 2.0.1.

    Possible values:

    • true
    • false

    The default value is true.

    hbase.regionserver.wal.durable.sync

    Whether to disable the WAL file durability to make the WAL data persistence on disks. If this parameter is set to true, HBase performance is affected because each edited WAL file is synchronized to disks by hadoop fsync when being written to HBase.

    This parameter exists only in versions earlier than MRS 2.0.1.

    Possible values:

    • true
    • false

    The default value is true.
