@ed day You can get the version information from Ambari UI. Click on Admin -> Stack and Versions and you will find the version information under Version tab.

@ripunjay godhani For service logs , log directory is controlled by a configuration property. You can modify the configuration property . Look at https://cwiki.apache.org/confluence/display/AMBARI/Modify+configurations for more details. You will have to restart the service for the changes to take effect.

@Simon Elliston Ball Thanks for information, I have a connecting issue When i try to query the table it does not return me the rows. Is i am doing something wrong result_schema = StructType([StructField("ID", StringType(), False),StructField("COMPONENT", StringType(),False),StructField("TOTAL_TESTS", IntegerType(), False) myrdd = sc.parallelize([final_table_text]) df=sqlContext.createDataFrame(myrdd,result_schema) df.registerTempTable("result_query") abc=sqlContext.sql("select * from result_query") print abc The output is : DataFrame[ID: string, COMPONENT: string, TOTAL_TESTS: int]

I am using pyspark to print filtered data as table. final_table_text = "\n".join(table_text_list) table_prefix='%table' print """%s %s"""% (table_prefix,final_table_text) The first line in table_text_list is table header Now i want to do some order by on this data, for which one way which i thought of was to use registerAsTable. There there a way through which if i specify the line separator and the column separator, I can use registerAsTable

In zeppelin notebook, there are 2 paragraphs In paragraph 1 - I have a python script which gets value from a rest-api call and assign it to a variable. I used z.put("var1",var) to set the variable. In paragraph-2 , I am using %jdbc to run a sql query on a mysql table. e.g select abc from tb1 where name = '<variable>' Question is - How can i pass var1 to the query and replace <variable> with value of var1. Any hints will be helpful

@Rambabu Gupta Also cloudbreak is better in deploying HDP and Ambari over Cloud Infrastructures. It uses ambari blueprints
