I would tell you the challenges searching it is no big deal. As the log files are being continuously produced in various tiers with different types of information, the main challenge is to store and process this much data in an efficient manner to produce rich insights into the application and customer behavior. For example, A moderate web server will generate logs of size at least in GB’s for a month period. We cannot store this much of data into a relational database system. RDBMS systems can be very expensive and cheaper alternatives like MySQL cannot scale to the volume of data that is continuously being added. A better solution is to store all the log files in HDFS which stores data on commodity hardware, so it will be cost effective to store huge volumes (TBs or PBs) of log files in HDFS and Hadoop provides Mapreduce framework for parallel processing of these files. Hadoop eco system sub components Pig, Hive support various UDF’s that can be used to parse these unstructured log files and store them in structured format. read less
