According to the document "Log analysis using Splunk Hadoop connect" by Boulat Chainourov, Hadoop should be used on Virtual Machines for Windows OS, however, the problem in doing so is that performance is degraded. security is compromised. there is no free distribution for virtual machines. the Hadoop distributions are not tested for Virtual Machines. QUESTION 10 According to the analysis done in "Log analysis using Splunk Hadoop connect" by Boulat Chainourov, the correlation between the number of events in the log file of Windws and the number of updates per month shows that there is an increase in the number of log file events with the number of updates per month of Windows. every update is treated as a red flag by the log file analysis software. there is a high correlation between the number of log file events and number of updates per month of Windows. there is no correlation (in fact, a slighly negative correlation) between the number of log file events and number of updates per month of Windows
