HUE 配置參數優化

1、圖形頁面表展示限制爲5000，業務需要進行調整。

參數如下

/opt/cloudera/parcels/CDH-5.14.2-1.cdh5.14.2.p0.3/lib/hue/apps/beeswax/src/beeswax/server/hive_server2_lib.py

744  max_rows=5000
754  max_rows=5000
771  max_rows=5000
784  max_rows=5000

2、hue 下載限制調整

參數如下
/opt/cloudera/parcels/CDH/lib/hue/apps/beeswax/src/beeswax/conf.py +103

DOWNLOAD_CELL_LIMIT = Config(
102   key='download_cell_limit',
103   default=30000000,
104   type=int,
105   help=_t('A limit to the number of cells (rows * columns) that can be downloaded from a query '
106           '(e.g. - 10K rows * 1K columns = 10M cells.) '
107           'A value of -1 means there will be no limit.'))
