HICC displays dataRelated DesignsAdaptors and agentsOn each data generation end (basically on each node in the cluster), chukwa uses an agent to collect the data it is interested in. Each type of data is implemented by an adaptor, data Type (DataType ?) Specify in the corresponding configuration. By default, ch

If you encounter a situation where the agent cannot be shut down gracefully, an available temporary workaround is to modify the KILL-1 in the Chukwa script for each node to kill-9. Collector is also a similar control method. Basic command Introduction There are a lot of executable files in the bin directory. Here are just a few of the doc
